My choices would be:
Ric Flair - could be the year for him if this is his last run
The Road Warriors/Demolition - suprised Johnny Ace hasnt pulled striings to get his brp' in already
Randy Savage = cant see this one happening though - Savage has too much heat
Ted Dibiase - cant believe this man gets overlooked
Owen Hart - not sure his wife would be in favour of this though
Davey Boy Smith - Harry may hopefully be a fixture on the scene by 'Mania 24; could be used to set up a storyline
