Hellcat by the Immonens or Spider-Woman!
Black Cat working for the Collectors Club in the last/cancelled Defenders series was short but awesome. I'd buy a comic with these ingredients.
If that's not good enough I want "Pixie" written by Garth Ennis, with art by Juan Jose Ryp :)
I've been really liking Kate Bishop in the Hawkeye books. Since what's so great is the dynamic between the two, I think that, rather than her getting her own title, they should have a few issues of Hawkeye focus mostly on her. Heck, they're giving Pizza Dog his own issue.
