So I was thinking about how in the game Maplestory it is possible to edit the appearance of equipment by simply swapping some images in the core files of the game. Is something similar even possible with eso? Obviously it would not be nearly as simple as it is in maplestory since it is a 2d game and less encrypted. So to reiterate the question, is it possible to edit the core files of eso in order to change the models or textures of different things. For example taking the texture/model of a Breton heavy helm and overwriting it with the texture and model of a Xyvkin light helm. Such a thing would be completely client sided however.
