hear me out, what if we make Wally West the main Flash of the DCU and make Barry Allen the veteran Flash. We could have the flash movie where Barry is a Veteran Flash who finds out his brother in law or nephew (whatever relation they have in this universe) also has Super speed and trains him as Kid flash and then at the end of the movie, Barry get injured, leaving the mantle of the Flash to be open. West takes over as the Flash, maybe temporarily at first, Barry could maybe return for a Justice League movie and then permanently retire from being the Flash. Then Wally west is the permanent flash.
