Sally certainly should be the Flash. She is great at it!

In all seriousness, don't think this would work. A Birds of Prey origin would be nice though. At least with the characters we have right now. I always feel Black Lightning would carry the legacy of Arrow as he leads the New Team Arrow AKA the Outsiders.
