Probably no one, considering Vince will not put over TNA stars (I'm assuming this: WCW in 2001). If someone would get over simply based on the Wrestler:
Jay Lethal - Could lead into a nice role on Smackdown! and would blend in well with a lot of that undercard.
Hernandez and Homicide (LAX) - Both of these guys are something the WWE should approach in outbreaching toward demographs.
Christian Cage - Vince never shuts the door without leaving a window open.
Abyss - Vince loves the monster type, and Abyss could thrive. He's a little undersized for the monster type, but I imagine he could do something.
AJ Styles - Big time babyface potential in WWE for him, and I think he could really come in and fulfill some of Rey Jr. coattails.
Robert Roode - I think he is training himself in TNA for an eventual WWE run. He is becoming a better worker, and his mic ability has progressed so much that he might be the most prime candidate in TNA.
