Battle of the elements

I got an idea for a good map (I hope) everything seems to be able to make, but one thing: all mages should be Bloodmages (with different skins and name).
Now to my question: Is there any way to make an bloodmage to have different paths? like an ice mage have the bloodmage path, and then for an lightning mage could I give him another path but that still uses the bloodmage modell? or do I have to download an bloodmage and give it another path and then give the downloaded model the new skin?

I guess that the most easiest way is to open up a bloodmage model and then just put it in different paths with skins matching the model. then my only problem is to get a bloodmage model. could anyone tell me how to get a model?

Extracting the model shouldn't be a problem, just download WinMPQ and search for the model file. About the different paths, I think that you should just edit a little bit of the model, add something related to the specific element. Nice idea, although many people used the "Element Fight" idea alot(at least like I saw it), but you can try.
