The Star Wars Audio Projects section of the An Index Of Projects & Help Thread for Star Wars Preservations… may be of help in narrowing down your search mate - or hopefully point you to what you are looking for.
For some reason ABC’s fine work came to mind when I read your post - it could be worth checking out his projects? Good luck with finding what you are searching for.
I ended up finding the project i was looking for, and it turns out it’s either unavailable, or was never released (https://originaltrilogy.com/topic/JOHN-WILLIAMS-Star-Wars-Episode-VI-Return-of-the-Jedi-RemasteredRemixed-Edition-Released/id/14606/page/3#1398070)
If you happen to have this or know someone with it in flac, please tell me.
i’m also looking for the club & dub mixes of latpi nek in lossless form
