I went ahead and uploaded the mod I wanted only so anyone who cares can take a look easier:
https://drive.google.com/open?id=1BQKd5 ... 3az8lWWiTl (disclaimer: I don't own this mod at all and in case there's a problem with me uploading a part of it without permission from the author, I'll remove it; just let me know)
Yes I did as I said on the OP, I deleted all the NiTextureEffects I could find on the models and changed the _nm's to _n, but all it did was make it look very dark and weird.

I didn't download the whole archive but have a look in your meshes: if you find a NiTextureEffect node with a CG_SPHERE_MAP reference that points to a glowmap texture, remove it. It makes stuff look overshiny in OpenMW
I'll try that when I get home, and post the results as soon as possible. Thanks everyone for chiming in, I really appreciate it!
EDIT: I couldn't find any "CG_SPHERE_MAP" refs in the models, so no luck there. I've played a bit with nifskope and pretty much all I managed to to was make the model look a little brighter and remove the gloss, but it still isn't rendering like it's supposed to. Bummer.
