3) Shane McMahon
Here's the idea: Shane O'Mac returns...but big daddy V (Vince not Vader), is not really happy with how his son hasn't been around to help the company lately. So he puts him in a match with ... wait for it... The Lethal Weapon Steve Blackman. Ok, maybe not Blackman, but any excuse to get him in a match, because Shane could really pull off a spot when he needed to. It would be great for one night only. Shane's a Raw legend, and was apart of some of the biggest story lines of the '98-'01 period when it blew WCW out of the water. He deserves his spot on this list.
Chance of Appearance: 90% (He's family, surely he'll show up for this, it's a big deal)
