Would it be possible to weld one of the player's hands to an Attachment such that the character moves with it almost like a ragdoll?

[MSDLF (Masol)]

I’m thinking of attaching the player’s hands to attachments on a steering wheel both attachments called LARM and RARM.

What I want is to have the hand look like it’s steering the wheel while keeping the body of the character intact.

Is this possible? Or too complicated. Does anyone know?
