Unofficial patches that are actually better than the official ones.
Mods that remove the blocky look in EVERY character's face(which is the source of a lot of the game's ugliness, just sayin.)
Mods that make the character's eyes look like actual eyes and not a blurred mess.
Mods that make the characters' uncovered bodies look like they actually bathe.
Mods that make the trees look more like trees.
And so forth.
What I'm suggesting is that Bethesda track down some of the best and simplest of these mods, get the creators on board, and group them together in a free DLC pack for PS3/360/PC. Kind of a General Improvement Pack.
Quite frankly, I'd be happy just having the characters' blocky/pointy/lumpy/StarvedCheekboneShadow faces be fixed, something that could probably be applied in a patch.(just adding one extra skin complexion to the character creator could fix this)
