I don't think this will happen, at least not next season. Granted, I CAN imagine the show making Wally the lead one day. In the comics, doesn't Wally become The Flash, taking over the mantle from Barry? Either way, it depends on if Grant Gustin ever wants to bow out while the show is still running.
