If I was to make a fan edit, I think I would change the prequel titles minus Revenge of the Sith. Just to mirror the original trilogy like The Phantom Menace should be ‘A New Threat’ and Attack of the Clones should be ‘The Republic Strikes Back’
Far too on the nose.
The titles already do parallel one another.
The Phantom Menance and A New Hope both describe the rise of a new heroic or villainous force that will define the galaxy.
Attack of the Clones and The Empire Strikes Back both describe the victory of the stated faction, and ties into how the Republic became the Empire, rather then the Empire taking over the Republic.
Revenge of the Sith and Return of the Jedi are of course about the victory of each opposing Force religion.
I have considered alternative titles. “A Vergence in the Force” and “The Chosen One” are ones I’ve considered for TPM.
