[General] Help with skins!

[iron_maiden244]

So I need help with importing skins, so for example this skin I wanna use has a path right? eg., Textures/Hero_BloodElf, How can I make it so that it doesn't replace the original skin (Default Blood Mage) Because I have many skins that have the same path but I wanna use them all for a map im making, can anyone possibly help? It would be really appreciated^^
sorry if this has been asked alot.
