You can use Team Blu or Harmy’s 97 preservation instead of the TV capture if you want HD quality over authenticity. And since you’re using Despecialized, I imagine you do.
Also, Towne32 was kind enough to PM me a version of 2.7 with the ANH crawl if you want to save some work. I’m not sure if he’s released it anywhere else or not. But if not, I’m sure one of us could help you out.
As for Special Features, I know several users here have made Special Features discs loaded with documentaries and such for use as bonus discs in custom Blu-ray sets like this. Look around the forums.
