I would like to see the similar characters to that of Mcduffie's JLA run under a high profile creative team. Someone like Gary Frank or Phil Jimenez would be my wishful choices. The cast should be much more diverse and not look so "black and white". There should be strong interaction; enough to be turned into good chemistry among the roster. I would like to see both Earthly and cosmic story-arcs, which there would be rotations of these characters on these stories.
My lineup would be Superman, Batman, Wonder Woman, Green Lantern (John Stewart), Firestorm (Jason Rusch), Doctor Light, Vixen and Zatanna. This would definitely appeal to people, who aren't so familiar with some of these characters like they are with the big seven.
