Just to clarify in no uncertain terms, you are not allowed to release DLC assets without requiring people to have the DLC. [edit] I'm pretty sure you're not allowed to release original assets at all, though I may be wrong [/edit] I really don't think that the 'But I changed the workshop info' defence will cut any mustard with Bethesda, and likely not with Nexus. Referring to the vanilla textures does sound like a much better idea, but releasing the unmodified meshes (despite the .nif being modified) might still get you in trouble. But why not PM or Email one of the Nexus admins and (on the Bethesda forums) one of the Bethesda community managers, so you actually get the real answer rather than the opinions of a bunch of people who'd very much like your mod? At best you get a definitive all clear that you can cite if anyone claims your mod is breaking the rules. At worst, you save yourself wasted time, work, and a ban from Nexus. Unless, of course, you'd rather not have the real answer.
