So earlier this year I was working on an Xcom mod that I lost some momentum with due to some programming/scripting issues that I have now resolved.
Xcom was/is one of my favorite games I've ever played, OpenXcom is a community modding project, that resolves many bugs and adds many quality of life fixes.
I've often noticed that the randomised unit portrait's selection pool is fairly small and limited, and so I am seeking to add additional portraits to add a bit of visual variety.
We'll see where this goes, I may ditch religious headgear, as the naming convention can mean you end up with a Sikh named Mohammed or the like.
I'll update this once there is progress, ideally I'd like to push this as an addition to the vanilla experience.
