Two other things to consider including. The original theatrical trailer would be a simple edit to do. (Using the Criterion LD as a guide.) The added bit for the reissue touting the stereo soundtrack after the Japanese eatery scene is easy enough to cut, and you might be able to clean up the distributor logo at the end of the LD trailer enough to be usable. (I think the trailer even on the Blu Ray is SD?)

Also, the Criterion has some nice animated graphic intros to the still gallery and trailer you might want to use. The stills from the DVD could be inserted over the lower quality LD images.

Anyway, it's just an idea! :)
