Bumping this thread. I haven't played with the creation kit so I don't know how this would work but... Since you can join the dawnguard as a werewolf, how about a mod that just assigns all NPCs under the dawnguard faction as werewolves. Tell them to shift upon entering combat. Have it work with moonlight tales and it would make dawnguard a lot more epic, especially that final battle if you sided with them. Just imagine all the npcs shifting right as you are about to storm Volkihar castle
