Interesting art, I'm not sure I'd want a whole comic of it.
About the team itself: I wish they would have gone with a different outfit for Firestar. I liked her 90's outfit, with the little jacket. It would also add a bit more variety since, if I recall right, it was predominantly red. We have two red heads dressed in yellow here. Seems a bit much.
Also two cat-based people. Couldn't they have dragged a fairly underused X-female (Dazzler? Nocturne?) in or something?
We have two zappy characters, two agile/cat-like characters. I would have much rather seen some physical beef or something different. It just seems like a very weird team. I like the idea, but I can't help but think maybe throwing in Mirage (is she repowered?) Songbird, or someone else interesting might have been better. (I thought Firestar retired anyhow...)
All that said, it still seems like an interesting team.
