One minor change I made was cutting the time for Michael Cole vs Jerry Lawler, because the match was suppose to be an attraction and not the focus. Cole and Lawler was designed to give Jerry his Wrestlemania moment and cutting the time would help do that in my book. Another minor change I made was cutting the two multi person matches and switching them to United States and Intercontinental Championship matches instead. The one thing I was unsure how to work in was a Women's Championship match and I think maybe a pre-show battle royal could work with a segment during the show to give some women there moment on the big stage with Snooki.
Speaking of Snooki the biggest change I would make is eliminating The Rock's presence from the show and push him back to the next night on Raw. The main reason is because Wrestlemania is the biggest show of the year and not something that should be used to promote the next year especially if it takes focus off the current year. In my opinion, Snooki could've been the special guest star for the show instead of The Rock and the focus could've been left of the shoulders of The Miz and John Cena to make the show sell. Then on the following episode of Raw the focus could then shift to Cena vs Rock with Wrestlemania 27 in the rear view and 28 in the windshield. It might be some small details and some might say Rock was the only thing good about Wrestlemania 27 well that's a problem cause WWE used him as a cop out then to avoid trying to put together a good show and promote it, they wanted Rock to sell it for them.
