I'm kinda wondering will the "Batgirl" - if it gets made - will that be a prequel set a few years ago whereas "Birds of Prey" will feature Oracle, Barbara in a wheelchair, in the 'current present' of the movies. Sort of like with Wonder Woman. They introduced her in a ~team movie BvS then she got her origin movie set during WWI. If so, then they could have a bit more range with casting Barbara.
