This is really interesting what you write.
Thanks 
I think this question is very interesting in general, also to understand how the mods works in BG3.

A gaming buddy of mine wrote yesterday she have about 80 / 90 mods and is fine with it. She can't say how many could be installed .... she thinks: "
Until your computer still are fine with it."
(I have right now about 58 + 12 (overwride folder) = 70 mods. And just about 4 or 5 loose file-mods. I was just curious about this question.)
