You’re welcome. Unfortunately, variables and various settings are all I’m good with right now - the really interesting and complex stuff is beyond me.
To answer your questions, you cannot actually remap LootSets. You can remap supply crates, but that only affects those descending from the sky and found in caves. It won’t affect dinosaurs. The easiest way would be to directly copy the supply crates and set their min/max quality multipliers to 0.
Drops from dinos are fairly simple, they are defined under “death inventory templates” in Dino_Character_BPs. If you want to remove quality w/o removing actual drops, just set the “quality multiplier per level” (or something similar sounding) found close by to 0 - this should make all dropped items have a quality of 0 (a.k.a. equivalent to engram).
Unfortunately, this would either require a copy-remap of dinos or a Total Conversion type mod.
