I'm working on one right now for the KC Planet comicon in Feb. After much internal debate, I opted to go wingless for the practicalities of walkingaround a crowded convention hall while wrangling my three kids. But the compromise that I made was to do the full exoskeleton and Chitauri gun so it looks like it came right off the wing superstructure. My oldest son is going as HC spidey, so it should be fun.
