Is there a way to have random AI troops generated by computer in XCOM 2 be FULLY random in appearance?

Question

From what I can tell in Xcom EU and Xcom 2, the computer random generated troops that you can hire from are "random" in name and such but overall are limited to a set pool of created appearances. You will eventually start looping through the same looking soldiers if you go through enough.

Is there a way in the .ini files (or another way, I suppose) so that the computer generates truly random troops- going through each customizable option- skin tone, hair, each wardrobe choice, etc- and choosing from 1 to the full number of options?

I would love to see completely random troops to choose from, not just a large but recurring pool-

Answer 1

By default, new units:

• Never have tattoos, facepaint, or scars
• Never have weapon or armor camo
• Have hair-color, skin-color, and armor-color chosen from an extremely limited pool
• Always have the same eye color(!!)

Fortunately, a very handsome author has recently created a mod for making rookies much more random: Rookie Customization Options

Answer 2

Even a fully-random generator will start looping through repeat appearances, since there are a only finite number of available possibilities from the available parts - and, statistically, you're likely to start seeing repeats much quicker than you might think. I suspect that that's what's happening when you notice that you're "looping through the same looking soldiers".

I traced back the soldier-generation functions in the source-code that comes with the mod tools and couldn't find anything loading pregenerated appearances; it just calls RandomizeSetBodyPart(...) repeatedly for each body part. That's exactly what I'd expect a fully-random generator to look like.

As additional evidence, I had these soldiers show up as recruits (and neither is in my character pool, so they must come from the standard soldier generator):

The former uses a lower-face prop from Capnbubs Accessories Pack, and the latter has glasses under a full-face helmet (from the Free The Hood mod). Neither of these are possible in an unmodded game, so neither can have been pregenerated by Firaxis; the only way they could show up in my game is to be generated on-the-fly when a new soldier is added to the recruits list.
