Ya! Let us know how it goes.
What I have done before(with extremely varied results) is to make whatever kind of beer you want next, no experimenting.
When you rack to secondary, pitch your "5 grain Frankenstein Ale" on the yeast cake. No it won't make an award winning brew, but at that point it is virtually free to brew and you will get a real good idea of how that stuff tastes and what it might do in conjunction with more typical ingredients.
I have ended up with 1 pile of crap, 1 brew that is basically a type of rum, 1 good brew, and 1 world class beer through just that kind of "afterthought" experiment. Good luck!
