I think I would have to be a Truthwatcher - Illusions and Healing would be immense

So I just read The Emperor's Soul for the first time. I know Brandon said that he tried not to stray too close to Soulcasting, but there are obvious similarities. The big difference seems to be that Soulcasting takes place in the cognitive real whereas Shai says that Forging affects the spiritual realm. With that in mind - could Shallan/Jasnah learn to apply their talents to the spiritual realm and therefore alter human souls? They're already communicating with the souls of objects so it doesn't seem like too much of a stretch.
