One idea I have always thought about was Lucas could have done the prequels backwards. My idea for each movie. III- Anakin fights in the Clone Wars, has the babies, becomes Darth Vader.(We all knew it was going to happen anyways, get it out of the way.) II- Clone Wars, Anakin fights in the Clone Wars, we find out how the Clone Wars started, we learn that Anakin is carrying around tons of hatred and fear because of the death of his mother, which the details are intentionally kept secret from us. We do not find out how she died. Anakin relentlessly hunts the Sith with the help of Palpatine. We do not know why he is so crazy about hunting them. I- Anakin as a teen, Obi and Qui-Gon find him. So we need a huge revelation or shocking twist for the final episode, here is one, Palpatine had Anakin's mother killed by a Sith, or Palpatine killed her himself. That is why he is so crazy about hunting the Sith.
