A mod to play as a Dwemer would have to be pretty in-depth to satisfy me really. As in, you may as well remake Skyrim with them specifically in mind.
Personally I don't believe there's any room for them lore-wise, since I'm pretty sold on the idea that they were utterly destroyed in such manner as to make it as impossible as impossible could possibly be to return. And if they weren't, the likelihood of them even WANTING to return is slim. They were tampering with the fabric of the cosmos for a reason, and it didn't involve making Resdayn into a theme park for gods.
Of course, wielding the Soul Calibur isn't lore-friendly either, but still fun as hell. Just not in first-person. Blocks half your view.
