Unfortunately I've not been able to get that to work correctly in combination with other mods I'm running. I know there are other similar NPC editing mods out there but just using one alone doesn't cut it, and using 2 or more in combinations always seems to cause issues for me. At the moment I'm using NPC and Alien Diversity pack from Stellarexile and N-Drews K1 Alien pack, its seems to be the most stable combination, but still has the odd weird texture scramble on some Taris commoner NPCs. Galaxy of Faces was also okay, but again, it doesn't play nice with the other two and by itself I felt a little underwhelmed.
I think this is the strength CapitaineSpoque project though, its improving on a lot of things simultaneously so there shouldn't be any of these weird mod clashes. I'm pleased to hear a lot of aliens and assets from TSL have already been ported over, because in my opinion the way to make the original KOTOR planets feel 'alive and vibrant' is to see visual diversity reflected across the NPC inhabitants. My biggest complaint of the original game even back in 2002 was the immersion breaking 'cloned heads'.
