Do not remove them.
Clean Saves Aren't. The only truly clean save is one made before the mod in question was even installed.
Even BGS recommends against yanking out modules.
Think of it this way... Would you, right now while your computer is on, yank out the video card?
Did you create a save file before your first dlc playthrough?
Start a new character. It's the only way. Unless you want to corrupt your current character's save beyond fixing.
Never remove a DLC during a character's playthrough, ever. And if you do remove it. Never re-load a character whose data contains said DLC until said DLC is re-activated.
