It would be interesting, however it is quite unlikely. CG has shown pretty often that they usually add characters based on what's currently hot on the bank as far as shows and stuff goes, so unless the SWToR MMO blows up exponentially over a course of just weeks, I don't see CG caring about it enough to add anything from it.
But in the unlikely case they do, the dread masters would be a great idea. The biggest issue however would be that there is 6 of them and they typically balance squads around 5 units, so they'd have to make two of them both strong and useful, but different enough to warrant one use in one game mode and the other's use in another.
