Different Texture for Demon hunter Alternate Animations

[hemmedo]

Hi guys

I want my demon hunter model to change its texture when I use metamorphosis.
I'm using Ujimasa's new textured demon form edit of the original demon hunter model. I followed Flux's tutorial here regarding to this issue; Change Model Texture Using Alternate Animations

But I think his way doesn't work for different animations since demon hunter alternate uses different ones. Is it possible to make this without using second demon hunter model that uses the texture I want?... Which I'm trying to avoid in order to save space?
