I'm interested in joining in.  Have a concept of a universe where something something happened to join a different version of the Marvel Universe with the DC universe during WW2, and set some several years after that in a world that hasn't known anywhere near as much peace as ours.

Superman/Captain America except not the Super Soldier from Amalgam
Wolverine/Punisher except sort of neither of them
Joker/Sabretooth/Kraven but from Russia
Bane/Colossus but German
Batman stuff whereby Bruce Wayne is sort of a Rich Indiana Jones type trying to find artifacts from the joining of the universes while his wards handle things.

I'd be fine with writing a bad guy if that would be more helpful or if any of these ideas seem particularly to fill a niche.  It's been sort of a group of ideas that came together after I saw this thread and thought hell yeah, I need in.
