^ Hmm maybe I'm wrong or maybe I didn't understand what you want to say.
Movie composers never edit film scores from album versions, but some of them edit them from experiments that are studio exclusives.
I think that some hollywood composers spend much time for the recording before thinking about editing the tracks for the movie. They call it the "Recording Sessions", you certainly know it.
For example Hans Zimmer made more than 16 hours of experimental music for Dark Phoenix, with long suites that finally ended up being short builds in the actual CD. Same for Pirates of the Caribbean etc.
Same for Steve Jablonsky, a good example would be Battleship with way more expressive music in the recording sessions than in the final product.
Also, "We Have to Go" from Transformers 5 and later released "We Have to Go/Ospreys" is a good example that shows how he created a suite that he had in mind before editing it to fit the movie. (Incredible track, oh yeah).
And basically, Hiroyuki Sawano creates many variations that he puts in a single long track, that is later divided in several short pieces scattered on different episodes. Yeah I know, this guy's way of working is very questionable but still...
Trying to dilute this post in order not to be classified as off topic: YK's El Cazador de la Bruja to cite only one example, I don't think that she seated in front of the TV show's sketchs and said: oh I can just put some shorts BGMs there and there. She really explored the world beyond the anime scenes.
Unlike FSN/HF, it looks like she just wanted to make tracks fitting scenes -very well, and I have to applause- but without going any further...
