How could we solve a problem with this mod?

In summary, it is a mod that allows you to see your body in the first person. Like Enhanced Camera.

But hands do not use the default position of the game (they are lowered).

Is there no way to fix this?

I know how to mod with the Construction Set but I have never modified anything with OpenMW.
