I'm not necessarily disagreeing with you as I may not fully understand what you're suggesting, but aren't the model joints and limbs actually bones, which are just Blitz pivots, which are children of the model entity.
You should be able to use FindChild to identify which bone is which, assuming entitynames have been assigned to identify the individual bones. Once you have the entity handles for the bones you can then use the standard entity position and rotation commands to get and set the attributes of the bones.
