I believe those are credited to RebRob41, so I'd either have to reach out to him for permission or make my own... since he's a rather hard guy to reach out to nowadays I think I'll risk making my own.
I'm going to say no, though you could attempt to install his mod AFTER my mod so his work overwrites my own.
I can promise you this; I do intend to use Heyorange's mod as a base for my own Sith Officer mod. Imagine it as the same quality as Heyorange's mod but with my own twist to it, and it'd be 100% compatible with this mod.
What I can't promise you is the release date for this.
It should be compatible, my mod doesn't touch those NPCs.
I've investigated it, I must say the problem is immediately obvious to me.
The reason being is that the file in question "tar03_blackv038.utc" is modified several times over across several modules so it's difficult to pinpoint which one exactly is breaking and why exactly it's breaking. At absolute worst this bug is causing a single Black Vulkar to remain unaffected, this shouldn't impact the quality of the game in any noticeable way or would it crash your game.
When a solution to this problem is discovered, it shall be fixed immediately.
