After taking greater inventory of things, here’s my plan for V6 at present. I welcome feedback!

Move ‘plot to destroy the Jedi’ to before Anakin coming in after briefing
If he agrees, I’d love to use Siliconmaster482’s audio for Padme’s Ruminations, and his version of R2 versus the super battle droid (which removes the electric shock)
I could add some Force-choke neck cracking sounds as Anakin chokes Padme out. ROTS clearly establishes she’s all right, so that her death can be completely for psychological/emotional reasons. These sounds could help sell that she is seriously injured and could die from complications later on.
I will attempt, and see what I think about, adding the interior long shot of the massacre in the Jedi Temple and a closeup shot of Anakin’s face
I will attempt to use DominicCobb’s idea to remove lines “along with all the senators” and “the council’s next move will be against the senate” to help us track with Anakin’s inner thought life as well as a sane person could
Put back in the tiny snippet of Grievous laughing and coughing (once) while his escape pod flees at the beginning, partly to remove the awkward “the music budget ran out” moment
Angel has agreed to see about replacing Bail Organa being summoned via viewscreen to a Senate session with an audio-only version
This is less important, but Angel may provide an empty dashboard to replace Bail’s hologram as Obi-Wan reaches out via Grievous’s ship
Angel may provide a version of the Vader mask being placed on Anakin with the mouthpiece in the ‘right’ place (harmonica style)
I will play around with reinstating Boga’s introduction
Reinstate line “he’s too dangerous to be left alive” from Windu
If Mala is cool with it, borrow his audio for Anakin being appointed to the council, using an eerie Imerial March rather than Anakin rambling
Reinstate dialogue from Anakin: “The Jedi turned against me; don’t you turn against me.” Rational thoughts? No, but it tracks with his character at that point. (Anakin’s a strong contender for Borderline Personality Disorder.)
Due to the thematic, if not more, relevance for Episode IX, reinstate Palpatine’s lines, “…to create life…” and “To cheat death is a power only once has achieved, but… I know we can discover the secret.”
I would love to be able to augment Chewbacca’s appearance, perhaps by recoloring his fur to grey
Reinstate air traffic tower collapse in full as Grievous’s ship comes to a stop on the landing strip
I would love to see R2 and 3PO removed from the birth of the twins
I will probably reincorporate Palpatine suggesting Anakin kill Dooku, though with no hesitation or “dew it”
I will probably include a truncated scene of Anakin and Padme on the balcony at night after all
I will probably include a truncated scene of Anakin and Padme in her apartment where Anakin becomes suspicious of Obi-Wan and expresses his disorientation (no nightmare talk, though) (scene placed immediately after the third ‘seeds of rebellion’ scene)
It is looking very doubtful that the Yoda/Qui-Gon scene can be extended or improved upon, though I regret not being able to feature more explicit feelings of failure from Yoda, given his appearance in TLJ.

This will probably not be done soon, but I am taking a modular approach so that I can pick things up whenever I can and make progress.
