DarkStar isn't for everyone. I get that. I take no offense to you leaving this mod behind. The good thing is, this mod does NOT edit any vanilla equipment or weapons. So, just equip anything that isn't Mk.II or Mk.III. Make a hard save at a safe location, like just outside the Lodge. Then log out, uninstall DarkStar, and move on. When you log back in, your safe equipment will be equipped and all DarkStar-generated equipment will be cleaned out of your save. Easy peasy.
