From the DC list, Wonder Woman and Green Arrow are the only ones that would interest me (even with Hawkeye's claim on the trick archer title now, I think you could find a way to do Ollie distinctly.)
The Marvel list - all of the above. Black Panther would work best getting in a future Avengers movie, Luke Cage as part of an ensemble; Heroes For Hire or better yet, Marvel Knights. Imagine a buddy movie with him, Iron Fist, Daredevil and Punisher all doing their thing in New York and then having to come together...Brian Bendis would be giddy!
