Ok so Babs would either be a regular librarian or running her own bookstore & café without the wheelchair-bound part, because here there's no Joker who permanently disabled her. Currently resides in Brooklyn, NY.
Cass is just a regular middle-class Chinese citizen.
Steph is a world famous softball & ping-pong (table tennis) athlete. She reached this title a few months after Dr. Strange sent Peter to the DCU.
Duke is a critically acclaimed film director. He directed a lot of Hollywood films & most of them are major box office hits. Like Steph, he reached this status months after Dr. Strange spell. Currently lives in Europe along with his mom & stepdad. (In canon, one of Duke's 3 interests/hobbies are films, so him being a director feels fitting. The other 2 are collectible card games & puzzles)
So yeah, apart from Dick & Jason who died, the rest of the BatFam are relatively doing well, despite having no connections/relationships whatsoever with each other.
Its so evil how well everyone is doing, especially with those evil evil lines of "a few months after peter left" HOW DARE
Cass (and babs) not being a ballerina is CRIMINAL tho!!
I also think it'd be cool if Duke directs like. Blum House movie esque movies. Specifically envisioning those escape room movies bc of him and his puzzles
They're so happy its weird,,, dc is just pain and misery 😭 the only way they're happy is if they're apart omg
