I found the albums that were made from DVD rips and they weren't spectacular, as expected. The main problem is that they use the film as a guide (as I mentioned earlier, because its probably impossible to know the music's original order due to how edited it was for the theatrical release). The albums also don't seem to have any of the material from the actual OST album mixed in, most likely because the rips from the DVD are so edited that only bits here and there seem familiar from the official soundtrack. The only project regarding this score that I see possible at this time is as follows:
Step 1. Someone musically experienced should do a new rip of the music in the film and learn the material backwards and forwards.
Step 2. They could then combine the bits of the album present in the film with the rips to form tracks as devoid of sound effects and dialogue as possible.
3. Then, the parts of the album not used in the film could be labeled as unused, and placed as well in the album's timeline as possible using their knowledge of the material, the script and the track titles as a starting point.
I'd love to give this a go, but have absolutely no time for such a project. Perhaps I'll have time in the future, or maybe somone wants to take this monster on.
Who knows, maybe GoodMusician is a fan of the score (although he seems very busy as of late)...
