With so many of the Justice League members being overpowered, we would never see such weak villains in a JL film. It would likely be a Darkseid level threat or something similar in which, physically speaking, Batman would be utterly and completely useless.
With that said, Bats is a great mind. He's got the tech and tactical ability to remain somewhat useful. I'm not sure it would be cool to see a movie with Batman in a control room somewhere as opposed to the frontlines though.
One of the gripes I had with the Avengers was Captain America taking a backseat to everyone. His heroics included two scenes and he wasn't that important compared to what I thought he should've been. I imagine Batman would be in a similar situation. I would think he'd stay to the shadows more throughout the film than fight in the open, unless he had a bat plane or some thing he could mow down baddies with.
