Trying to add a mesh parented to an armature to another instance of the same armature

Question

So I have my base model/rig, and from that model I created prefabs w$$anonymous$$ch are basically copies of the original with different clothes toggled on or off.

I just added a new hair-mesh to the base model/rig. I want to add t$$anonymous$$s new hair mesh to some of my prefabs, so what I did was

1) drag a whole new copy of the original rig, LowPolyModel, into the prefab, Cas$$anonymous$$er

2) right clicked and unpacked the new copy of LowPolyModel completely

3) pulled over the two new hair meshes from LowPolyModel onto Cas$$anonymous$$er, updated the root bone to use the root bone of Cas$$anonymous$$er and then deleted copied instance of LowPolyModel from the prefab

After step three, the hair meshes disappear. The game objects are there, but the meshes are invisible. I suspect that these game objects or the skinned mesh renderer is still referencing somet$$anonymous$$ng from the now deleted LowPolyModel instance.

It also seems like I can't add the mesh manually with a new gameobject/skinned mesh renderer. There's another step that I'm either missing or isn't in the inspector.

Does anyone know how I can go about doing t$$anonymous$$s? I rather not have to re-do my entire prefab every time I add new hair or clothes.

Thank you.
