I don't think they could win, or well I think they could but they probably wouldn't..
Let me just try to figure out how they would though, just for the sake of an argument
Exar charges NJO Luke. Revan uses the force to keep the rest away possibly freeze them or whatever when they are frozen he helps Exar take care of Luke. They should be able to pull it off before the rest comes out. If they succeed its a walk in the park from them. Either Exar or Revan will face Mace and Obi while the other faces Yoda, doesn't matter what happens they will die.
But because I don't think those Jedi will let something like that happen I really don't give Exar and Revan that much of a chance
