9. Chris Jericho
Chris Jericho is exactly the kind of guy who can drop in on WWE as and when he pleases. An easy nights work in which he comes out for a big cheer on the thirtieth anniversary of Wrestlemania is sure to appeal to Jericho. He now mainly focuses on his rock music but a one off Mania showing is easy enough for him to accommodate. The Andre the Giant Memorial Battle Royal is the perfect way for WWE and Jericho to work together. It's zero commitment but for one night only it would be beneficial to everyone concerned. Jericho will add name value and thus credibility to the contest, with his assured style of wrestling helping to give the quality of action a coherent narrative. Jericho is brilliant in these types of clustered matches and has proved it time and time again in lengthy Royal Rumble outings. I always recall Raw TLC in the fall of 2002, Jericho carried a concussed Bubba Ray through all the action of the latter stages of that match. You need a ring general like Y2J in battle royal type matches, Wrestlemania 30 would be much better off with him.
