Hey, if you're into checking items off a list, Legacy of the Dragonborn might squeeze some more hours out of skyrim for you. It's about creating a museum with everything in the game. You have to get pretty much everything, from a leather armor set to daedric weaponry, and store it in the museum. You can still keep the cool items by making replicas for the museum instead(and you can always take the item back from the museum also). It's been a while since I played so maybe some things have changed in newer versions, but after finishing that mod I pretty much put down skyrim - nothing else to do at that point (other than mods with new quests, or skill/perk overhauls)
