Well, let's see...
Power Pack: Too close to The Incredibles.
Squadron Supreme/Supreme Power, Moon Knight, Spider Woman Jessica Drew, Luke Cage, Cloak and Dagger, Runaways: Too dark for the Disney Brand
She-Hulk, Carol Danvers: Tad too racy for the Disney Brand
Squirrel Girl: Possible problems with Fox, due to being a Mutant
Alpha Flight, New Mutants, X-Factor, Six Pack/X-Force, X-Statix, Generation X, NYX/District X, eXiles: Problems with Fox, due to association with the X-Men
Nova, Black Panther, Starjammers, Inhumans, New Warriors: Possible problems with Fox, due to associations with Fantastic Four (Via Silver Surfer and Galactus for Nova and New Warriors), and X-Men, also possible conflict with Sony for New Warriors due to associations with Spider-Man
Black Cat, Silver Sable, Spider-Woman Jessica Julie Carpenter, Spider Woman Mattie Franklin, Anya Curazon: Possible conflict with Sony due to associations with Spider-Man
Iron Fist: Would probably work better in live action, but could possibly be pitched against a hypothetical Kung Fu Panda 3
Great Lakes Avengers: Could work as a deconstructional parody of the superhero concept
Jessica Jones (Alias/The Pulse): Too many "mature" themes for the Disney Brand
The only animated Marvel properties I could see Disney doing are Iron Fist, Great Lakes Avengers (Minus Squirrel Girl and probably Big Bertha) and the Marvel Animals (Spider-Ham et al) and possibly Patsy Walker: Hellcat.
