I have been toying with this alternate history scenario for quite a while now, in which after the culmination of their Crisis on Infinite Earths event, the legacy, or sidekick generation takes over the roles of the more established heroes of the DC Universe. Dick Grayson becomes Batman. Donna Troy becomes Wonder Woman. Wally West goes down the same road that he did in our timeline. Kal El dies instead of Kara Zor El in CoIE #7 and Supergirl becomes the matriarch of the Superman franchise as Superwoman. These former sidekicks would form the new Justice League of America, along with leftovers from Infinity Inc, The Outsiders, and the New Teen Titans.

This paradigm shift would be seen in the media as well. Dick Grayson would be the Batman introduced in Tim Burton's eponymous 1989 film of the same name, etcetera.

This wouldn't be the case for every character who had a title at that time. Silver Age characters such as Hal Jordan, would still resume their titles as they lack a real legacy counterpart (unless you count John or Guy, but I always considered them to be roughly the same age as Hal). A select few older characters who have had never truly felt great success in the past, such as Aquaman or Green Arrow, would continue their mantles for a select period of time. The legacy characters in this new continuity, who haven't been killed off or retired, would form a new, contemporary iteration of the Justice Society.

Would you have liked this to have happened in retrospect? Do you think this would have succeeded?
