All of this is possible, but it's hard to say if any of it would actually hit especially with how fickle the current gaming audience is. Batman multiverse is a bad idea though, people are getting multiverse fatigue.
If I had to personally pick, I'd want to see a dark knight returns based game, but kill the justice league would ruin the momentum of a game like that.
I don’t mean multiverse i mean, just break down all the batman tropes and make it part of the story. We all know the bat-lore and ethos of the character, turn it on its head, make Bruce wayne the dusty old man in the chair, and have Terry subvert all the expectations of a typical Batman story.
Imagine a BB game with something more in the style of a Gravity Rush, but dark and cyberpunk-ish.
