Mine is sort of outrageous but my first mod will consist of a leprechaun who will run throughout the Skyrim woodlands. He will most likely be a scaled down Wood Elf with a custom green outfit complete with top hat. If the player spots him while adventuring, they will have a chance to stalk him until he returns to a spot in the forest where he hides his pot of gold. Then the player could forcefully take it from him or persuade him to give the player a portion, either option won't be easy.
