More Heads and Diversity is a great mod and follows the most purist way to mod the game, and here's where i was concerned, even with the Upscale, the meshes was still vanilla and that means that they have the same old problems, so i always wondered what would happen if this mod get the fixes from the Familiar Faces and also including the Pluginless Khajiit Wiskers and glowing eyes, i decided to make my idea come to reality since it didn't had an improved version. So i fixed many of the problems the More Heads had and also changed some of the terrible textures using some of my edits, also i made some changes to some of the meshes because of the textures (the Khajiit has some odd eyes in the original mod).
For the meshes i've found some heads numbered 21 that wasn't being used from More Heads, so i fixed and added them.
For the textures i've added some compression and mipmaps, now they are optimized and don't weight 200mb anymore.

This mod is a patch that i made for the More Heads and Diversity mod, but having it isn't a requirement, if you want diversity you'll still need to install the original mod esp.

If you already have Pluginless Khajiit Head Pack, it will ask to replace some files, it's the same files, i only added them in order to not add any requirement.
Even tho it's called a patch it doesn't need any of the main mods to work.

Recommended mods:
This will sound a little dumb but, yes, i recommend to use with Familiar Faces and replace the Khajiit with the Pluginless Khajiit Head Pack, there's no need to use the Upscale or the More Heads unless you wan't to use Diversity.
