I think they need to at least add the Romulan species and costume options. You might be able to costume bad Rommie mob groups as Good Rommies and roleplay it that way, but it would be a pain.
The real solution is being able to set the mobs to either good or bad. Another Neverwinter feature that would be nice to see added to Star Trek Online.
