Switch looks for npc's ovarhaul

[Seraficzny]

Hey guys. I've recently downloaded NPC overhaul mod (https://www.nexusmods.com/skyrim/mods/97349?tab=description) and loved the look of some NPCs but didn't like the way these were distributed among them (e.g Mikael looks great but it's a waste of appearance if you just see him once in a game). So i was wondering if i could give his appearance to another NPC. I've tried applying Mikaels meshes and textures to other NPCs by changing name of the file respective to the ID of NPC (taking into concideration race and gender) but in game they end up looking distorted (some vanilla grey face and bald). Creation Kit doesn't show proper in game look of Mikael when previewed, although all custom mod head parts are clearly in game directory and not in bsa, so I cannot export it. Tried changing qualities of NPCs, so they would be identical to vanilla Mikael and later work on them but the result was also distorted faces. The only file left in the mod is the ESP one, so I assume it is somehow responsible for the issue but I can't find info on how to edit them, providing I can do that in the first place. Please help since gosh I've tried to solve it for long, instead of playing the game xd
