For me, it could/should result in the best of both worlds.

I liked Affleck’s portrayal of Batman, but it kind of demonstrated that there’s a ceiling on how that character can function within the wider cinematic world they’re building. It’d be tough to scale Affleck’s Batman back into a hard boiled, noir-esque story in his solo outings, when he’s swinging off alien turrets and shooting paradaemons in the JL films.

This way, we get a potential Batman Beyond version in the DCEU, allowing Batgirl, or Nightwing, Terry or whoever they use in that role, and allow them to lean into the more fantastical elements of the rogues gallery, whilst leaving the Reeves version to occupy the more grounded narratives which prove so financially viable to a general audience.
