There was a Cosmic Avengers group! If you haven't read Avengers:Infinity by Stern, you need to - it's fantastic. In fact my team was pretty much the Infinity team, but I had to stop putting all of them in it . . .
Just a warning, Starfox is on the team. Though if you dislike him because you think he's too cutesy, he does have a moment at the very end that you might think is interesting.
