Idea that someone could do

Someone could geoset Arthas's head onto evil Arthas's deathknight model, I havn't seen it done and people always want an arthas on a horse, so I thought it would be a good idea. This isn't really a request, its more of an idea.

Dude, just reskin Evil Arthas with blond hair and normal skin pigment. No need to merge them, they're just about exactly the same.

actually they pretty much are, the portraits all you reall need to change

The portrait is what I ment.

Yeah, so you just change Arthas' portrait path so it links to the death knight.
