As far as my solution is concerned, if you can arrange to not require the second speed potion to be taken either, leaving the room as is would be fine - not taking the potion should grant an optimization bonus. Rheb would make three different sequential versions of the room, each requiring one of the three solutions.
Continuing the theme, here's a demo for Jungle Heat 1N without using the speed potion. (I really like how you color-coded the orbs and doors in the Entrance!)
