I think this will probably happen one day. Ideally, if WWE bought TNA, I would hope they would just keep running it on Spike TV. They simply don't have room for even 5 new main event wrestlers right now. Especially on RAW. If they could use the main guys on the WWE shows and PPV's when they wanted to, but 80% of the guys would never see TV if Vince tried to do what he did with WCW/ECW. If they did this they could actually have real Bragging Rights and interpromotional matches like they claim we are getting with RAW and Smackdown.
To answer you question:
A J Styles
Kurt Angle
Sting
Beer Money
Motor City Machine Guns
Desmond Wolf
Abyss
Matt Morgan
Hernandes
Mr. Kennedy (I wish Kennedy was still in WWE, there might be some issues with bringing him back)
I would also buy out the contracts of Hogan, Flair, and Bischoff. I wouldn't want them on TV every week, but it would be nice to see them on special occasions.
RVD and Jeff Hardy quite WWE because they hated it. I don't see Vince welcoming them back with open arms. However, if he thought there was some money to be made, we would see them again.
