Is it possible that Darth Sion was actually Lucien Draay?

As it said in the title, is it possible that Darth Sion (Lord of Pain) is actually Lucien Draay even though that is not said in wiki. It says that Sion fought on Exar Kun's side during the Great Sith war and so on, but there is one scene in Knights of the Old Republic comic where Draay is shown on some random moon where is says that he will embrace his destiny as Lord of Pain, and that is the last scene with him.

I havent finished with reading, but that just crossed my mind, because the timeline could fit, also Draay could have joined Revan during Mandalorian wars and on
