I can't remember who off the top of my head, but someone did this last year at NHC San Diego. They made a beer with 99 yeasts. I think it was supposed to be every yeast available from Wyeast or White Labs (or both?).
If I recall they made a stout with it, so something already pretty flavorful. Possibly also something lighter like a pale ale? I was expecting it to be super fruity esters from all the belgian and english yeasts but it was really unremarkable. I think once you get to that point, so many of the things have different temp ranges and likes and dislikes that you're not really getting "everything" from each yeast strain. One or two that are in their ideal ranges will dominate the rest of them. Pretty impressive attempt though.
I like fruity IPAs so your brew sounds right up my alley.
