Well, I don’t think the Imperial March really fits, there is other music that fits better.
The Song Battle of Hoth
Imperial Starfleet Deployed & City In The Clouds
Betrayal at Bespin
The Imperial Probe & Aboard The Executor
Emperor Arrives
Nute and Rune confer with Darth Sidious
I would even skip the Obi vs. Vader fight entirely, up to where Vader jerkily turns his head.
Cut inquisitors extremely, except for Reva, she is unfortunately a leading role.
The helmet on the jaw chin does not fit.
All Obi-wan should know is that vader is a machine, a diabolical machine.
Good ideas, I think you just have to wait for the series to finish, then use what’s useful.
Oh, one more thing, Bail should only report on the radio, Obi wan’s cave should remain secret
