Can I use my own head mesh and migrate my own head mesh into MetaHuman?

Now I have a face mesh which is obtained from scanning and registration. Is it possible to use my head mesh in metahuman? I would like to use my own head mesh while still use the skeleton, weights, etc. in order to use the expression system of MetaHuman.

Is it possible?

What I have tried:
I exported the head of metahuman as FBX. I rigidly aligned my own mesh to the metahuman head using Warp3. I transfered bones and weights to my own mesh using Blender. Finally the generated FBX was imported into UE4 and I connected Amination, BluePrint, etc. to the new head. But the head does not move with Live Link. Something must be wrong in this process…

I believe you also have to add the live link BP to the body as well because the head movement is driven from there and not the face mesh.

Thank you! Actually I only need the expression system. Do you mean that driving facial expression relies on the body? Is it possible that I drive the face mesh only regardless of the head roation?

The head rotation comes from the body, I’m using faceware with live link, if I only add the blueprint to the face mesh for the animation mode it doesn’t rotate the head, if I add the faceware blueprint to the body animation as well it then drives the head as well.
