[quote=@Eddie Brock]Hmmm. The people want a Flash, eh? Although, while I agree that the JLA should have actual JLA members, I also worry that we're going to have a lot of PC Leaguers and comparatively few Avengers (whenever they arise) at this rate.[/quote]

A mixture of Marvel/DC on both would be great.

Here's my rough idea: at some point Lex is uncovered as a fraud and/or something goes wrong and somebody (we'll work that out) dies, forcing Superman's hand into starting a team of his own - The Avengers. In all likelihood it'll be a short term thing until the League is "reclaimed" from Luthor and then we'll have an expanded JLA rather than two teams awkwardly coexisting.
