Seeing that the “Extended Death Star” battle is now no longer being a thing, could it be a possible deleted scene under your Bluray Special Features?
There’s a hell of a lot of work that would be involved in recreating that whole scene in HD and i feel it would be time best spent on working on finishing the trilogy, so it’s a no i’m afraid.
That’s all good. Even if you do include the original 480p version that you created, I’m sure that will be more than enough. Most films have deleted scenes that look rough compared to the finished product anyway so it wouldn’t be an issue IMHO…
