WARNING: The following contains major spoilers for The Batman, now in theaters.
In Matt Reeves' The Batman, Robert Pattinson's Bruce Wayne didn't hide how overwhelmed he was with crime festering in a rotting Gotham. At the beginning of the movie, he admitted he couldn't be everywhere, which is why he worked with Catwoman, and by the time the film ended, he knew he needed help more than ever when the city begins to rebuild, but she left town. As such, given what fans have seen in decades of lore, The Batman has drastically changed the foundation for the Bat-family's introduction for the better.
Usually, Bruce expanding ranks comes from a place of privilege or ego, with Bruce realizing he has to save teens and turn them into soldiers. It creates a weird power dynamic where they must listen to him no matter what, which could scar them, as the Titans TV series showed. He believes he's helping them, but it's irresponsible, toxic and dangerous, as weaponizing angst, grief and trauma like that won't actually help them get over their emotional problems.
However, following Riddler flooding Gotham, this Bruce knows better. He became a beacon of hope, someone who needed to step out into the light and no longer live in the shadows. It's why he worked as a first responder in the climax and inspired others to do the same. Now, with that mentality and understanding of what paragons of virtue are about, Bruce is better positioned to hire allies rather than subordinates.
After all, he's desperate and can tell they're necessary if he's to protect the city. Viewing them as equals would be a massive upgrade because he could better connect with them on a human level, and by understanding the public and these allies, Bruce can better carry out his mission genuinely. For instance, Tim Drake can help with teen outreach, Dick Grayson can be a second-in-command, Batgirl can work with Jim Gordon's cops, Batwoman can work with women under siege, and Duke Thomas can help with communities of color.
It'd fit the grounded essence of this filmverse, while sticking to its social justice and equality messages, making these folks more than just sidekicks. This respect and camaraderie would create a better-balanced unit for the power vacuum that exists, stymieing corrupt forces like the Penguin, or even Joker and Riddler, all because Bruce would now have a true family alongside him.
See how a better Bat-family can be built after The Batman, now in theaters.
