Off the top of my head, they are:
Mandy Rose (it's been said that Khan is a huge fan of the Divas Era)
Kevin Dunn (they are reportedly good friends as even though Dunn disliked most of the WWE wrestlers, he does have a soft spot for Khan)
Bron Breaker (expected to be Roman Reigns' successor)...
I think it's gonna be Vince McMahon and Kevin Dunn IMO. I also expect Bruce Pritchard to have some say regarding which NXT talents to push but I do think that Triple H's days as NXT showrunner is coming to an end.
