Doesnt the armor in ALL fantasy RPGs look like that already? I mean, oversized and overly ornate? Im sure someone could use the models already in the game to come up with something pretty close. Its the texture that would be difficult.
Hey, at least a blade couldn't get anywhere within... Oh, 2 feet? of you.
That looks like it could be made by smushing Daedric and Dwemer together, with some inspiration from Adamantium maybe. The textures are simple gold-ish, with the borders having a gloss or environment map applied?
