How about a hunting guild of some sort? Like the bards college, not a major one like the mages guild but just another few side quests with unique, magical animals. Hunt them and craft rare armor.
Heres an idea, a quest could have been included in Heathfire, you go hunting with your adopted child, or your spouse. Todd Howard talked about how they obsess over the little details. What about this? Its a snowy, gritty 'kill your own food' kind of place for god sakes.
I feel Bethesda missed a great opportunity to include more roleplaying aspects surrounding hunting. It could have been another incredible little sidequest, or minigame. A few little AI tweaks, who knows it could have been a whole new thing.
