This should be possible if you change the skin files in your war3mpq. To do this, you need a MPQ-Editor like MPQ2k, but at least I don't know how to change the path of imported files.
If you success to do so, the skins on your computer should standardly look as the imported ones, because you change the standard! :lol:
All in all: it should be possible but I don't know exactly how. :?
