I just downloaded a weapon mod and I want to change its texture with the vanilla weapon model. Is it possible? and if it is, how can I do that?

The mod is called "Blackrazor - Legendary Soul-Devouring Greatsword"

here's the link:

Its using the sword of chaos model, and I want to change its model into Voss' Silver Sword. However the "Blackrazor" is a greatsword and "Voss' Silver Sword" is a longsword is it possible?
