Marvel has done this and Star Wars could do so much better. Some examples are what if Anakin never turned to the dark side? What if Ahsoka turned to the dark side? What if Jar Jar was the Sith Lord? What if General Grievous killed Kenobi? There is so much more that could be done as well such as What if Yoda killed Darth Sidious? This is something I know a lot of Star Wars fans would love to see.
