Now, I'm fairly confident it's possible for me to score diamond on Tower W, a tower I obtained platinum on last year.
It's definitely possible. It's possible for W to be the first diamond you get, however it's definitely more knowledge gated than many other first diamond possibilities.

×* Have enough keys for all five of the yellow/blue/red/purple/platinum key caches and the return route from the nexus. After carefully adding up all the keys, mandatory doors, plus doors to multiplier items (I can provide the list of these on request), I conclude this would require skipping all the optional door shortcuts and hp/atk/def loot rooms along the way, everywhere. Also the two feathers on F14, unless these are paid for via keys from the nexus (that aren't on the path to acquiring the return key).
Exactly how much leeway is there? If I counted correctly, there may be one extra yellow and red key somewhere along the way. Also, one blue key must be acquired in the nexus (which is along the usual path to the return key, or elsewhere if using diamond medals). Of course, picking up even more keys in the nexus could soften this constraint.

×Pick one of those 5 caches and give up on it. You need one of your key colors to be your throw-away key choice, as at numerous places you will be forced to open mandatory doors and be given a choice of color. The correct choice to give up on the cache is:

×red. This doesn't mean you can't partially open the red cache, you just won't get close to the end of it.
Don't skip the two feathers on F14. You can get most of the multiplier items on the way up the tower, at worst some may have to be delayed a while.
Generally key use is very inflexible because of the caches. It's multipliers, the main big key chain caches, continentals, and backtracking out of the nexus that you want to spend keys on. Most everything else is off-limits until really late. This isn't a comprehensive list, e.g. you have to spend keys to get a plat key at some point. Some doors are required.
You do want to spend medals on keys in the nexus. Specifically you want:

×As many yellows as you can get, especially the ones on the 3rd nexus floor that also has a load of stats and potions. You can leave it until you can kill the enemy guarding it. The earlier you can open the big yellow key feather cache, the easier things will be. It doesn't matter if this results in excess keys at the end of the tower, the less high-tier shadow enemies you need to reach and kill to open that cache, the better. Violets from the nexus are also nice if you can spare any medals.

×* Skip the continental potions (even desirably on 5F) till 32F. Also the eternal potion on 20F. Get it after all the continental potions, when the platinum keys are needed to finish clearing out the cache on F32.

×Skipping the 20F eternal is correct. You can't skip the 10F one because you're required to come back to do the left-hand side of the first 5 floors, so spending the violet to skip it just isn't worth it. Violets are too tight. You want to save continental potions if you can, but the reality is you're going to have to drink a bunch of them on the way up the tower because you're going to drain health at around 16F-20F no matter what. You just get clobbered. However, the more you can save until after the dreamer, the better. You will also be saving the Eternal until after the dreamer (taking HP for the level ups after beating the dreamer ends you with more HP than before the fight) so you just aren't opening the final 2 platinum key doors until the very end.

×* Pick up HP levels at the end. Maybe before, maybe after, fighting the boss enemies on F32, or both.

×This is correct. The more sunstones and medals you have, the earlier you can take HP levels at the end, but leaving HP levels until after the dreamer is good enough for a Diamond.
However, none of these are the main unintuitive gimmick of the tower, which you haven't stumbled across, and to be fair, you won't by just planning ahead on the tower. I'll try and drop a series of successive hints, but it's hard to hint without just spoiling it.

×The tower is split into 6 "layers", a new layer every 5 floors (with the nexus stage being the 6th). Each layer has its own tiers of enemies. How the stats of these enemies progress each tier is very important.

×You can't really compare enemies across towers because every tower has its own balance and stat progression, but W's is a little unusual for the stat growth you get in the tower. Specifically, from the "night layer" (16F onwards), both the slasher and fighter enemies get unusually large DEF and HP. Normally slashers have low HP to value building ATK, and fighters have high HP to value building DEF. But here, they both get big HP values.

×The main gimmick of W is called the "DEF switch". Due to the way the stats of the enemies progress, you are required to suddenly change your strategy to building DEF. But then the nexus layer wants you to have ATK, so you actually only build DEF in the mid-game and then swap back to ATK. If you don't do this and just keep building ATK the whole time, you will bleed so much health you will be forced to basically drink every continental potion and will score terribly.
However, the tower is very sneaky about this because of the final rangers and the high DEF values of the main enemies. When you reach the night layer, you won't be able to fight anything and you'll be getting smacked by Final Rangers for like 60k-80k damage and clearly the rangers want you to build ATK. I actually abandoned the DEF switch first time trying the tower after being told about it because I assumed it couldn't possibly be right and I needed more ATK, but I was wrong, this caused me to be over 10m off of the diamond requirement. The amount of HP lost in the meteor layer if you keep going for ATK from your level ups is just too huge.

×The timing of when to do the DEF switch and when to go back to ATK are not obvious and happen earlier than you might think. Specifically you want:

×To start taking DEF level ups when you reach 1,000 ATK, then swap back to leveling ATK when you reach 4,400 DEF, which is when Final Fighters become free.
