If Undertaker vs Chris Jericho can't Happen, who should Undertaker vs at WrestleMania 28?

CM Punk as both men have excellent mike work, Punk is an exceptional heel and Taker is an exceptional face, the match would be a classic, and Taker could retire undefeated and on a great match, look good since Punk is an underrated top notch worker, and give CM Punk his ultimate much needed "Wrestlemania Moment". Punk could again show why he is 1 of if not the best in the world all around at what he does, and they could put on a classic for the ages, especially if for 1 night Punk's moveset wasn't wattered down and casual fans could see what us hardcore fans saw in the indies moveset wise from Punk in FCW, IWA and especially ROH! This match could cement CM Punk to potential legendary status, and instead of being an every once and a while main eventer, could be a consistant face of the company like his immence talent matches after a high profiled match with the phenom! The 2 already have chemistry from working together on Smackdown, HIAC 2009 and Breaking Point!
