That sounds like a real nightmare to work with. I've never been a big fan of such extensive overhauling. I try to keep my mods to a minimum, and make sure I'm as aware as possible of what all they affect. I love plug-in-less retexturing mods, because as long as I like how everything that's been retextured looks, I don't have to worry about it. If I take some textures out and load up a save, it won't be dirtied by the act. The game will just look more vanilla than it did before. I love that. It's clean and easy.
I also love mods that don't cover a very wide range in the game, such as mods that add armor to a couple of leveled lists or one particular merchant or something. I don't use HELLUVA because it's just too much. I have to be able to remember what at least 90% of the changes are that result from any given mod I have installed/active, and all these huge mods aren't conducive to that. There's also the fact that if I had the time and the skills, I would mod just about every single aspect of Morrowind myself rather than use other people's work to enhance my gaming experience. I'd have very, very few mods by other people if I could help it. Not because other modders svck compared to me (quite the opposite, actually), but because I'm just so damn picky.
