Cool mock up Anakin.
I also think you could do the same with Maul, and use him in most of Sidious’ scenes instead like you’ve done with Dooku. With both Maul and Dooku, you could possibly use lines from The Clone Wars where it might be appropriate, and cut those scenes liberally to the essentials.

Another thing I think would be a cool change to TPM would be to turn Qui-Gon and Maul’s first duel on Tatooine into a night/twilight scene. Seeing their lightsabers stand out in the dark would have a nice look, and maybe you could add a few of Tatooine’s moons and a few stars in the last shot of their ship flying away as Maul watches it.
You also might have to regrade some of the previous scenes to imply that dusk was approaching as well.
