Is it possible to have Anakin rush at the Count and fight him a bit (no lighting just taking the fight from later in the sequence), have Dooku bring the ceiling down blocking him in (taken from his fight with Yoda) then have Obi-Wan fight a bit and almost lose then have Anakin recover and climb out of some added rubble to save Obi-Wan?
On a separate issue might it be possible to re-create this version :
of Shaak Ti's death using the other available deleted scene of Grievous killing her and footage and backgrounds from elsewhere in the film.
Vader doesn't kill enough Jedi on screen.
