Comics Question

Lately I've been thinking about comics. I've always wanted to write a superhero comic, and I hope that someday it will happen. Maybe something with Green Arrow, maybe something team-related. Marvel or DC, it doesn't matter. And I'm curious; how many of you think about the same thing? If you're a writer--assuming you're a comics fan--what characters would you like to play with? Alternatively, if you're not a writer, what writer(s) would you like to see take a crack at which character(s)?
