I would love to see it happen but not now. A few years in the future when both of the universe have been established. DC's cinematic universe isn't fleshed out enough yet.
Btw, Raven and Martian Manhunter would absolutely obliterate Professor X and SW
DC needs to get their world straight first. The DKT was great (though Rises didn't measure up to the first two), Man of Steel was good but the Green Lantern was terrible. I need proper GL, Flash, and Wonder Woman films. They have two many icons that they need to stop screwing over. Then a Justice League movie on par with the Avengers.
