Joining different thickness wall in arched profiles

Ok, I can't seem to find a way to do this: I want to layer a recess with different wall thicknesses and materials, in an arched opening. Imagine a romanesque church entry with the thickest wall having stone on the outside, then a wall with a different material, and a third thinner wall set inside of that with yet another finish material, with punched openings, all with metal stud construction. I want the studs to wrap together and finishes to wrap to the next wall. I've tried cutting embedded walls, modifying profiles, using arched openings instead of profiles, and a combination of both. I've tried setting the studs inside the core and outside the core to try and wrap. Cutting out the wall doesn't allow wrapping, so that seems out. Using openings doesn't allow for walls to join/wrap correctly. I've even tried sweeps, but the materials won't have the studs and finishes. I've attached images of what I have.
Can anyone help?
