Man... I was thinking more about this offhand comment and I think it has real potential. It fills in the book slots and divys up a lot of the characters to a real place. Fill in missing characters with characters who don't have established generational homes and there you go.

Then find out where to squeeze in Namor, Northstar, and anyone else I forgot. I figure this will give everyone a chance to grow in a certain book. X-Force would make sense for some overlap. Each book gives the characters an established history and relationship to grow off of. Etc.
I kinda like this idea.
