How to land one object on top of another along with bones?

Question

Python

The mesh's parent of the landing object is bones (bones/armature). Mass map available
The main condition: it is necessary to lower it together with the bones. Those. the process of lowering the object must be calculated according to the mesh, but the bones move with it.
Considered options are both scripts and physics.
Attempts already made:

• Drop to ground script - doesn't want to drop the object
  
• physics Rigid Body - sends an object to another dimension
  

Answer 1

It seems to me that one cannot do without cunning self-written scripts.
For it is necessary to move the bones themselves (so that the mesh moves), but at the same time the volume must be taken from the mesh (so that there is a correct collision).
You can try to use ragdoll physics, but I have not worked with this thing and do not really understand what kind of simulation is required.
