#3 - Randy Orton

Speaking of guys who would be successful heels out on the independent scene...
Randy Orton being able to go out on the independent scene as a heel, where he can pretty much say and do whatever he wants would probably be amazing to watch, as I feel that his character has been severely limited in WWE, especially after they went PG.
One wrong move ruined his entire WWE career - Watch Now!
Plus, all of the independent wrestling fans would truly have disdain for the former WWE World Heavyweight Champion, which is pretty rare these days.
Obviously, a guy like Randy Orton will probably never leave WWE to go wrestle elsewhere, but everyone probably said the same thing about Chris Jericho before this year.
