Moving Hux’s speech and the Hosnian destruction is an interesting and actually pretty cool idea, but it kind of messes up the attack on the base. When do we learn that the base is a system killing weapon? Do we just show up at the Resistance base and suddenly everyone’s talking about it? One of the problems with the Starkiller base is it shows up late in the second half as sort of an underdeveloped subplot. Moving the speech and the weapon’s first use would not really help matters.
Keeping Hux’s speech where it is except in prep for the base to start sucking up a star would solve all of these concerns. It would establish the orders motive, how they use the base, establishes that it will be sucking a star until it’s single fire. And the reason the Resistancd is worried is because it’s sucking a freaking star (“massive disruptions in hyperspace”). By cutting certain snippets of dialogue in the base, the resistances concern with the base as a result of it beginning to suck a star feels like a logical continuation of the story.
Only solution I can figure is if Starkiller base is mentioned in the crawl
Another good idea that combined with the idea I had would make this plot restructure of moving the Hosnian destruction not a problem.
