I voiced a crazy idea long ways back for a Christmas quest where the player finds a dying guy in a Santa suit next to a motorcycle with sidecar (custom mesh), who with his last breath says he wanted to bring a Christmas greeting to [insert town]. Dieing in the players arms so to speak, the player can assume the dead guy's role and carry out his dieing wish, utilizing Pov's brilliant gift4kids mod.
Optionals (for added XP) would be to cover as many towns as possible in one evening, making use of Nib's motorcycle mod (with a sack of toys in the sidecar)
Pimping the mod would entail that any and all companions are automatically dressed as elves -including Fawkes. Female companions get risque xmas-elf outfits, because I'm shallow
But, again, that's just trimmings.. pun intended.
