Changing Ancient Protector Uprooted textures only

[LaMBhE]

Hello ppl, I'm having a very simple request about modeling

Can someone modifying Ancient Protector model to a model that changes texture every time it morphed? (Like Mountain King when doing Avatar)

So, when Ancient Protector is going Uprooted, it changes appearance.

I can't do this thing via trigger because it's not for map, it's for a mod.

Here is the new texture:

Protector of the Pine - Wc3campaigns

Ty for the help,
