Brand Split worked when they basically had an overcrowded roster with the top stars of both WWF/E and WCW, but it sure as fuck wouldn't work with the depleted roster they have now.
Except you have Zayn, Breeze, Bull Dempsey, Baron Corbin, Kevin Owens, Hideo Itami, Finn Balor, Adrian Neville, Kalisto, Charlotte, Bayley, & Sasha Banks all who could get over if given the opportunity on a top tier or mid card level. The Vaudevillians could be a good mid-card heel tag team. CJ Parker would be a great jobber heel.
That's an INSANE amount of talent. Balor, Zayn, Owens, Itami, and Charlotte are all folks who could legitimately be top tier stars. Right now if they come up, that group is going to challenge Ziggler, Bryan, and Rollins for fandom. You already have to basically turn Balor to find him a slot.
