We’ve had storylines that fleshed out Bruce, two faces origin being one of the more popular ones, but I think the popular story is that Bruce is just an exaggerated character batman plays. Bruce doesn’t really exist anymore. Even the stories where we see batman costume free, the connections that seem real feel like they’re connecting to batman just with his mask off.

I’m also with you on your last point even if I think you were being sarcastic, personally not sure how the story of batman makes sense if he has a mutual loving support structure in his life. It would be interesting to see batman happy, but it just feels kind of like a story ender.

I’d still give your idea a read if it was made, but I’m definitely coming into it feeling kinda wary.
