[Star Wars]During the Battle of mustafar, obi-wan somehow convinces Anakin to return to the light. What happens next?

Either of two options happen. One, Anakin immediately turns and goes to stop Palpatine's plans, and either succeeds and thus prevents him from converting the Republic into the Empire, and the war continues until peace can be settled a few months later; or he fails and dies.

Two, he and Obi-Wan retreat and bide their time until Anakin is truly ready to face down the real Dark Lord of the Sith, and in the meantime pretty much the galaxy goes on much as it did in the original narrative, the Empire is formed, citizens are enslaved or genocided. Only instead of Darth Vader at his side, Palpatine has a different enforcer.
