The way the holograms are broken in the vanilla game does like this:
Head models and body models are two separate models whilst the head model is animated meaning there are parts inside the head to animate the mouth and the eyes.
The holograms makes the NPC transparent with a holographic filter, resulting in this 'hidden' bits being made visible to the player.
Admiralty Redux fixes this by taking the two separate models and merging them into one to fix the inside of the neck being visible and it removes those bits inside the head so that they aren't visible in the hologram.
Upon thinking about it, if you install ONLY the Proper Peragus Corpses and Peragus NPC Overhaul installs than this mod is compatible with the Admiralty mod. I'm actually going to update the mod page to specify this.
For the Tiered Peragus Miners install, there would have to be a patch for it though since I don't know how to fix the NPCs like the Admiralty mod does than it would have to be done by someone else.
DarthParametric would know how, though I doubt he would as he mainly focuses on the first game as he doesn't like the second game.
If any other modder would like to try, I'm more than happy to take it to the PMs to discuss it. All you'd need to do is merge the Czerka body model and the Armored Flight Suit model to the correct Peragus NPC heads and try to recreate what DP did for the Admiralty when it comes to fixing the heads.
