As far as technology acceleration, look no further than the first Death Star taking ~25 years and the second taking ~6 years to build.

And trust me: story is more important at Lucasfilm than continuity or canon technicalities. If you think it improves the story, that’s what you go with. Not everyone will agree with you, but it’s your cut. You’re the new director, you call the shots. If someone doesn’t like it, they can learn iMovie, Premiere Rush, Final Cut Pro, Premiere Pro, Avid Media First, or Avid Media Composer.

EDIT:

Also, if anyone has aspirations for a career in editing, Avid Media First is free and works exactly like the expensive Media Composer all the pros use. It is cantankerous and annoying, but it’s the real deal and it’s free.
