The LaserDisc also has this stereo mix.

LaserDisc sounds better since the VHS still has some noise but digital LaserDisc audio is CD-quality and sounds much clearer.
This actually sounds really great. Ironically, it sounds more stereophonic than the 5.1 remix on the Blu-ray/DVD.
I would definitely do a custom Blu-ray (and also custom DVD for the open matte 4:3 version) with this stereo remix, the original mono mix (from another LaserDisc) and the 5.1 remix from the Blu-ray.
