firstly, get wc3viewer
here . than follow my instructions
1) open up wc3viewer. then open the .mdx model of the accolyte.
2) then go to "current file" and select "remap textures"
3) click on the texture that applies to your model. in this case (i think) it would be textures\accolyte.
4) then click the "change" button. look for your skin. open it by clicking "open"
5) press ok.
6) your skin is now wrapped oto the accolyte.
good luck.
