There are a lot of mods that improve the gameplay features or add new quests without affecting performance at all. Excluding Morrowind Overhaul, almost all of those mods you mentioned in your list above should have no performance cost.
And I would imagine there are probably also some different texture mods that improve the appearance without as much performance cost as Morrowind Overhaul. That mod can make the game more demanding than modern 2012 games.
