It was easy to pick stuff out. I agree with basam's comment, if they don't screw with Heyman's booking, anybody on the list with a modicum of talent will shine. I just picked the following due to personal preference.

Matt Hardy
Paul London
Edge
Brian Kendrick
Kane (give him back his mask)
Gregory Helms
Eugene (as Nick Dinsmore. Fuck his retarded Retarded gimmick.)
Charlie Haas
Shelton Benjamin
Val Venis
William Regal
Lance Cade (I picked all of HBK's former pupils. I assume they'd work good matches against each other. Or maybe not.)
