Darth Revan isn't a Jedi, but Revan could kill Anakin. Luke could hold Mace and Yoda off for a while, probably long enough for Anakin to die. Revan then attacks Yoda and Luke fights Mace. Revan kills Yoda because Yoda was weakened by Luke. Revan, now throughly exausted, would need a brake for a few seconds and then Luke weakened by fighting Yoda and Mace would probably loose to Mace. Revan then finishes Mace.
Who mentioned Mace in first place??? Anyway, it would be TOO close to tell, i think te jedi would win because you have a 3 on 3 match, the sith are driven by anger and feelings while the jedi are calm and can "think" through the force of what theyre going to do, while the sith would only jump for it and start slashing randomly with their sabers, not to mention that if they have the chance they would kill their partners, so definitely the jedi on this one.
jedi win, Anakin wastes Dooku, NJO Luke can beat Revan, RotS Yoda can beat Sidious. Even if the Luke vs Revan and Yoda vs Sidious is a tie, then Anakin will be able to come and help whoever needs it, so say Luke vs Revan and Yoda & Anakin vs Sidious, then we get Luke, Yoda & Anakin vs Revan, Revan looses.
So the jedi can take this anyway you look at it, if you switched up the matches to Luke vs Sidious, Anakin vs Revan or Yoda vs Dooku, then Luke would beat Sidious probably before Revan would kill Anakin, then Luke vs Revan and Yoda vs Dooku, Yoda wins and we get Luke & Yoda vs Revan, Revan looses.
Or another combo, Yoda vs Revan, Luke vs Dooku, Anakin vs Sidious. In this, Dooku dies quickly, then we get Yoda vs Revan and Luke & Anakin vs Sidious. Finally we get Yoda, Luke & Anakin vs Revan.
No matter how you look at this, the jedi win
Sith win
Dooku takes out Anakin, yes I know he lost in ROTS but that was according to the books a staged fight besides he stopped using his own style and he didn't use the force to finish Anakin. So Dooku beats Anakin.
Then Luke vs Revan, this fight will be a stalemate for a very long time until Dooku joins Revan and they finish of Luke together.
At that time Yoda should have defeated Sidious but he stands no chance against Revan and Dooku
