Is it possible to use Metahuman heads on UE4 Skeleton?

My project was started in 4.27. I’ve kept up with upgrades to 5.4 but I’m still using the UE4 Skeleton for all my player and NPC skeletons. My player wear a lot of armor, so I just need the head to and would like to use the Metahuman heads to bring my characters to life.

I was wondering:
1.) How would I change the Metahuman skeleton to use the UE4 skeleton? I tried “Replace Skeleton” but there’s a ton of missing bones.

2.) I know Metahuman was developed originally in UE4 so I think some of the old models have UE4 skeletons, but I can’t find a way to download them from Metahuman Creator.

Here’s some more pics.



if you have version control, you can try injecting the new bones with UE5.4’s skeleton editor, see if can keep using the old animations with it
