Something that would be a game changer for the divergent canons would be the storyline for Star Wars: Underworld. This series sported a more direct involvement from Lucas, and actually had many scripted episodes. While I think it’s a stretch to say that Lucas’ rough ST treatments are exactly how it would have went down, having scripted episodes is much more final. Since the series would deal with young Han Solo and Palpatine, I expect some conflict with Solo and ROS. Also, I’ve mainly discounted TCW because Dave Filoni has basically called it “legends.” When there’s canon conflicts, he says it’s because it’s just the same event being told from a different point of view (or something to that effect). He doesn’t let the films or especially the EU get in the way of his story, which is fine, but overall makes it a more disconnected medium.
