For those who want a Character Pool to accompany these customizations, I have created a detailed 68 person pool that I couldn't quite make into a mod (because Modbuddy is as tamable as a raging Muton) but will make available for download here:

To install the character pool, simply place the bin file into your character pool archive folder, usually found here:
C:\Users\yourname\Documents\My Games\XCOM2 War of the Chosen\XComGame\CharacterPool\Importable

If you would like to read about the characters included in the pool, their character articles are included in a World Anvil archive of a story I am creating:
