Problem is I think Star Wars would be a better setting if they extended the war to a decade, had it occur naturally, and then had the reveal that Dooku and Sidious slipped inside and took it over from both sides of the conflict. It'd give legitimacy to the CIS way more.
Some SW fans can't grasp that the war was a false flag run by DARTH SIDIOUS and DARTH TYRANUS with the purpose of killing Jedi, giving SIDIOUS more power and installing Empire. They gaslit themselves into thinking a Sith Lord, who did 50 heinous acts in AotC alone, is a good guy.
