I suppose you could confide your idea to someone on the dev team to see if they think it is worth saving up for an SS. We still wouldn't relax the restriction that you have to have a hold with 8 or higher on the board already, but if it's an absolutely amazing concept then we could suggest that you try to get a great hold out there so you can save it for the SS. On the other hand, we might just say that it is just amazing enough to get you an 8, and to save some of your story and other ideas for the SS afterwards.
Or ask someone who has been here a long time and played most of the holds (like someone near the very top of the high scores list)...they could tell you if your idea is truly unique of if they've seen it before. You just have to decide if you can trust that person not to make holds with that idea. I think you can trust someone on the dev team or someone who has never made a hold before (since they aren't likely to steal your idea then) but it's always a risk, I suppose.
Game on,
