I like the story of bruce being batman without his money. Bruce being a street fighter like Ken Masters and his parents being alive would be nice and have a rivalry with Shiva who feels the same way beating strong oppenents sometimes saving the world other times not. Bruce in his later years instead of being holed up at home when he no longer can be batman physically actually teaches those with powers or not how to be heroes. Having a younger sister with magical powers and trying to protect her from the supernatural along side his girlfriend zatanna. Batman not having the no gun and not to kill ideals rescinded.
