Connecting Metahuman head with Mannequin skeleton

Hi Guys!

Has anyone managed to connect Metahuman head (with all its functionality in Unreal) to a different skeleton? I’ve tried it with neck and head bones, but the head part on the clavicle and upper chest area didn’t animate with the body part correctly. I know that in original Metahuman those parts are connected (somewhere in blueprint?) via couple bones at once. Can we do the same with different skeletons?
