Wasp is really an odd one, since of all characters she would seem the most natural for multiple different looks (at least until this modern era when costumes are redesigned every six months). I would most want her black and yellow costume, although that is a super easy quick custom. I agree that the Black Knight is perfect, but Herc and Shulkie could definitely use upgrades. I have said for years that the Avengers vs the Masters of Evil would have made for a perfect theme, especially back in the days of shared sets between TRU and the specialty market. Remember then? We didn't know how good we had it.
Going back to the thread theme, with Carlos Pacheco's untimely passing last week, I am reminded that a set based on his designs from Avengers Forever would be great, and a nice tribute to a fantastic artist.
