For me, the game won't start with all of them installed. Maybe there is a conflict with another mod I am using (some outfit replacers, the other 4k texture mod, some standalone outfits).
I don't think it's related because if there was a crash problem it would most likely happen when the game tries to load the character. You can always try to rename the files, try to append '_P' to all of them, this is something that other mods do and I didn't know this when I made this mod since I didn't see the need for it. And also mods are loaded in alphabetical order so if you want to change priorities you can rename files, the beginning of the alphabet is loaded first and will get overwritten by things loaded after.
Can't really tell since my fps is locked and I'm using a mod that prevents most assets streaming, it does certainly increase loading times a little bit.
