Can I change the mesh on a SkeletalMesh at runtime?

I would like to import SkeletalMeshes at runtime(clothes, with Daz Gen 8 skeletons).
I had a look around, but couldn’t find anything… or at least runtime(not allowed to use UE4 editor code in builds AFAIK)
The skeleton would be the same on each imported asset, and the anim and physics asset isn’t needed at all.
So I thought, instead of importing a SkeletalMesh I could just import a mesh as an fbx, and assign it to an existing SkeletalMesh in my scene.
Or something similar…
I found this.
Changing the path would be ok editor time, but not sure how to get this work at runtime.
Can someone direct me to the right blueprints or the right c++ stuff to look at please?
Any alternative way of getting clothes as SkeletalMeshes into game at runtime would be really great as well.

You simply want to load a fbx in runtime, you can check Marketplace for additional plugin:
