That's a very good thought. To me Darth Traya sounds like a female name. Bastila comes to mind. But I really like what you said. Kreia said that you need Darth Traya's. Maybe lightsided Revan suposedly joins the true Sith only to intentionally betray them in the end and defeat them. This could work to for the darksided Revan and it would be a legitimate betrayal, where as the lightsided Revan would just be a spy.
