When I see the Rus armors, I really think there should be a total remake of all the other textures.
EDIT: Although I think it would take ages to make them look as good, since the Rus guy probably sculpted his pieces and then made smooth height maps and specular maps. For a "next-gen" game those 2 maps are very important, they often give the detail and obviously sharpen the texture.
If you manage to get a nice result, I'd like to see what you did.
