If I'm not mistaken everything that happened during KOTOR1 wasn't flew by everybody's head until they actually told you who Revan was. Until that point, everything they said about you pondering on the moral of the storie's was a bunch of nonsense. So what I'm saying that in KOTOR nothing just happens randomly, it's there for a reason. I don't believe they would just put a head almost identical to one you could pick in KOTOR1. If you pay attention it even has a vertical scar on one side of the face just like the old one. The only difference being that it has a longer beard.
