Replacing character models (Corsairs: Return of the Legend)

I wanted to put the Blood model from patch 1.3.2 on the Damned by fate and it seemed to work out, BUT I ran into the following problems:
a) Cuirass are not displayed. He threw off the textures of the cuirasses, but at the same time they do not appear on the character
b) when taking the musket in hand, the character model disappears, you cannot move although the model with the musket is present and indicated. Again, in HeroDescribe in version 1.3.2, Blood's models are simply indicated, and in the Damned by Fate, he also entered with a musket, he also entered, but nothing.
