Custom texture on a standard hero.

I found this fantastic Blood Knight skin:

It's for Death Knights but I'm making a custom melee map(Humans -> Blood Elves, original I know!) but my issue that I can't figure a way to change the skin without changing the Undead Death Knight as well...

List of things I've tried:

Google.
Searching this forum for FAQs, which I could've failed at and if I did forgive me...FAILED.
Searching Hive Workshop...FAILED.
Tried attaching it to a paladin then switching the paladin model...FAILED.
Tried to use a custom model's custom texture...FAILED.

What I think I need to do is tell WE to attach the texture to a custom Death Knight model. I was planning to extract the Death Knight model and re-import it and then having the texture follow the new custom texture pact...unfortunately I forgot how to do that.

I......FAILED.

Try this.

Or alternatively you could use the Evil Arthas model which is basically identical, if you're not using it already.
