Do you think you could do a full on arcane crossover? Imagine Bruce Wayne in piltover/Zaun, those two cities are like Gotham where the rich and poor are practically at war. Wayne enterprises could be the richest company in piltover and their mansion would be on a secluded hill/small mountain away from the city(good for batcave) Bruce's family would be killed during the rebellion and he would be raised by Alfred, and during the funeral Bruce runs off and falls into a cave of bats.
And I'm thinking Wayne enterprises adds some modern tech to the city, like cars, phones, and security cameras(so the bat computer could eventually become a thing)
Batman would become everyone's fear, he would be in both piltover and Zaun during the night, stopping crimes and slowing down silco on one side and putting away corrupt cops on the other.
But a new enemy would emerge, the joker with his new mysterious side kick, Jinx. Eventually he finds out who jinx is and goes to vi so information, and vi agrees to help if she is let out, so batman breaks her out.(Takes place during episode 4)
So batman and vi form an unlikely duo, but when batman finds out that he'd have to wait outside (away from vi) where they need to go because his costume will give him away, he decides to take a risk change into Bruce so he can keep an eye of vi, so vi sees Bruce, but doesn't know who he is(just his face and first name, not how important he is)
That's all I got right now
