A few problems with your one, locky1. Firstly, Mercury's really not ready for a singles push - and secondly, Kennedy isn't fit to work matches at the moment. If it were me I'd go for something like:
Chris Benoit vs. John Bradshaw Layfield
Rey Mysterio vs. Mark Henry
Randy Orton vs. Hardcore Holly
Matt Hardy vs. Orlando Jordan
Let Benoit go over JBL due to Boogeyman's continued interference, have Henry beat Mysterio (Batista's tag partner) to keep that feud fresh - and have Orton go over clean to show his legitimacy. Then you have Hardy vs. Jordan where either could go over, although Hardy due to Booker T's interference seems logical. Sets up finals of:
Randy Orton vs. Matt Hardy
Chris Benoit vs. Mark Henry
Orton to beat Hardy because, logically, he's the guy you want holding the title. Then have Benoit pick up the 'shock' win by beating the much bigger man - setting up a Benoit vs. Orton match at Royal Rumble that's well hyped, features two good competitors, and would provide a legitimate champion regardless of the outcome.
