One possibility is that Batman brings some new tech to the Justice League. His gadgets could give the team an edge in battles. Also, his relationship with each member could be explored. He might have a deep conversation with Wonder Woman about justice and morality, or a friendly rivalry with Green Lantern in terms of who can handle a situation better.
In this fanfiction, Batman might show off his detective skills to the Justice League. He could solve a mystery that the other members couldn't. For example, he might find out the true identity of a new supervillain faster than Superman or The Flash.
Well, it could be that Batman has some conflicts with the Justice League at first. Maybe his methods of dealing with crime are too extreme for some of the members. But in the end, they come to understand and respect each other more, and they work together to save the world from a huge threat like Darkseid.
