Take the JLU cast and apply it to the Marvel universe as well, and find a happy medium between the two artist work. Storyline would be awesome if they had a sort of all out war that involved all those people like Dr. Doom, Luthor, etc. Of course, you have to have some Marvel vs DC action, like Superman vs Sentry, but then it'd probably end up being Supes/Cap as the two leaders with Batman and Reed saving the day in some way. That'd be awesome if they did this, but they won't lol.
It could be done, but it's questionable that they would. The way I see it, if they take both productive teams, but put the major DCAU heads on top (Bruce Timm, Andrea Romano, etc.), and go with the DCAU animated style, it could make for damn good movie (as long as they don't try to fit it into current DCAU continuity, which they did with that godawful Superman: Brainiac Attacks movie, which should be burned).

Not yet, Marvel's animation isn't up to par with the DCAU at the moment. Maybe after the new Marvel cartoons launch this year, we'll see some collaborations.
Which is why it would be best to allow DCAU's team to work in the animation, it would work a lot better that way.
