Also if Darth Malgus is notably different and said to occasionally be a cirtic of the Emperor at times...does that not hint at something? Malgus also with the revan-esque warriors... There might be a connection of some sort, but just what will have to remain a mystery for now. This is purely speculative.
Interesting theory, but the problem is that Malgus and all of those warriors are Sith. It has been confirmed that Revan left known space as a Jedi Knight, so his followers should also be warriors of the light. Also, I refuse to believe that he wore the Sith costume after the light side ending. It was a symbol of his identity as the Dark Lord of the Sith, and it just doesn't sit right with a redeemed Revan.
