A few months back, I made a trailer using the lost dialgoue, since it was implied by the novel and crawl to be some sort of Pre-film event heard throughout the Galaxy that prompted the rest of the film’s events. At this time, this is how I interpreted it.
Having said that, this new scene’s explanation/edit is a fantastic way to incorporate it. It fits very naturally, allows at least some of it to be heard, and fits with the idea that it’s still part of the larger plot as described in the novelization.
If you’re listening to community ideas, I think you really need to keep and use a cut like that somehow.
