Render shadow from different lod level

I have made a first person lod for my placeholder character. It’s the same model without the head and neck. However, I want to render the shadow from the third person lod so the character will not appear headless from the first person perspective. I am sure that this is possible, but I do not know how to achieve this.

Note: lod0 is the first person mesh, and lod1 is the third person mesh.

Solution:
I added a second skeletal mesh using lod1. I hid the mesh and enabled hidden shadow. I kept the inherited mesh to lod0, but with cast shadow disabled.
