Hello again,
I've got a few subtle changes for prequels, which somebody could use in his edit (especially for Revisited Team; I wanted to make some for that mock-up contest, but I'm skilled with photoshoping as Natalie Portman in acting)
Ep. I:
-C-3PO would be a Trade Federation droid, in place of TC-14. He would also replace Jar Jar through the whole movie. It is C-3PO (and R2, of course) who should bring humour, like in OT with his endless talking.
-eyes of Battle Droids should have some light, like 3PO's.
-give more/different facial expression to Neimoidians. They look like they were only moving their jaws up and down, and not talk.
Ep.II:
-cut all lines, where Fett is refered as "Jango". He shouldn't die in AotC and Boba should be made as his son/apprentice, not a clone. Watching film in order I-VI would give an impression that they're one person. Plus, also re-colouring armour to Boba's green.
-Obi-Wan should be using Qui-Gon's lightsaber (even in arena battle) and Anakin his lightsaber from RotS (cut the destruction of his sabre in droid foundry).
-one thing would be great in AotC. Scene with Dooku communicating with Sidious holographically. This would spoil the surprise "Dooku is working with Sidious", but nevertheless it's something worth trying.
-AotC would not end with the wedding or Palpatine watching Acclamators taking off to the battlefields. Dooku's arrival at Coruscant is what I have in mind, and Republic Fleet Ships in background, jumping in the hyperspace, as solar yacht enters the orbit. And when Dooku and Sidious finish the conversation, I would add an Emperor's laugh from RotJ, like the one from Palpatine's arrival at DS.
Ep.III:
-I always thought that Mustafar is the most unrealistic planet of all the saga. Everybody on that planet would die of the temperature or suffocate, because there are only volcanos and no plants to produce oxygen. This should be changed to at least a industrial, not volcanic, planet Mustafar or even to place the duel on industrial district of Coruscant. And the part of duel, when Obi and Anakin are fighting on that floating droids... they would burn alive that close to lava (or jumping off that giant antenna falling from lava fall)
-if someone is able to do that, I'll be thankful to him for the rest of my life: Lucas decided, that one of the greatest actors to star in Saga should be changed to CGI coughing droid, not even voiced by Gary Oldman. Christopher Lee, in my opinion, is one of the guys created to play villains. My plan was to cut Grievous from RotS, add Dooku and expand Dooku's plot. He would not be only the Jedi renegade, who became a Sith, but a spy, who would just pretend to be a Sith and get close enough to Sidious and destroy them forever. Dooku would redeem during duel with Obi-Wan on Utapau and tell him his scheme. Then Dooku would be killed in order 66 and Obi-Wan accused of treachery by collaborating with Dooku.
