Alpha Werewolves would be interesting. If there were packs that you could join, it'd be interesting if after the Alpha dies, you can make a bid for power (rather than the title being just given to you) and fight one of your fellow pack members for the top spot. It'd be a difficult boss fight, but a cool werewolf vs werewolf match to prove your dominance and earn the right to lead the pack. In addition to the title and a better home (supposing this was a community of werewolves living in a small village in the forested regions), you could get a special Totem of Hircine to give you a new Howl, a boost to your werewolf's stats upon transformation (eg, an extra 100 stamina and health) and wolf pelt clothing/armor to signify your status as head of the community.
I mean what if there were werewolves that were the first ones and could change whenever they want and that after centuries of people getting bit by them and then those guys getting bit by those then they would have forced transformations.
But werewolves already have the ability to transform at will. They just have the forced transformations when there is a full moon(s) or every night during the Bloodmoon. And going on the whole "These are the first werewolves so they're more powerful" road doesn't sit with me for two reasons. 1: It's too much like what we saw with Dawnguard's Vampire Lords, and 2: Unlike vampires, lycanthropes aren't immortal (at least as far as I know) so even if these werewolves existed, we wouldn't really be able to come across them unless they got that Corpus disease or some other means of immortality.
