Ultimates was hand on heart some of Hitch's best work. His Steve is gorgeous, and cries perfect emo tears, and his Tony is a ball of cheery insolence. The domestic violence scene is graphic, but I would say that narratively, that plot is handled pretty well by Millar.

She-Hulk would be great! Although I would like it if their first venture into superheroines was a character not quite so closely bound with a male hero - which is why Black Widow would be perfect, I think. (I know, Carol also has the Captain Marvel connection, but I think her story would easily work without him, especially as he hasn't appeared in movieverse, and she's less, um, thematically bound with him.) Oh, I also wouldn't mind Carol as she is in Ultimates - she's a Badass Normal there.

Yeah, Spider-Woman's origin isn't really connected to Spider-Man, but they might have sold the rights as a bundle?
