If I remember (i do not keep this game) :
file with HQ (high quality textures) have an specific oodle library and the other files of game have the other one.

I used a specific data file for HQ and install them as an optional feature.
I also use a bms script to extract wem files and keep only my language.

With only english and french , without HQ textures and bonus I'm at 56.9gb

What I've found out so far:

However some of the smaller hq patch files works better with the oodle library from game folder.

Average idtech engine experience.

Edit:
resources files

To make srep dedup takes effect for all the files, you have to use xtool as a standalone compressor without freearc and place freearc as a second step after xtool. Otherwise you will miss a load of duplicates if you precompress the files separately.
