I don't know if you can use shared topology with ACP shell and normal solid model mesh. I suppose if there was a common geometry model that shared topology, and the face was meshed in ACP and the solid was meshed in normal model it might work.
If not, you can always slice the common geometry and imprint features onto each geometry set so that mesh controls will allow a congruent mesh to be made in both models, and a node merge operation issued instead of using bonded contact.
If you can't manage to eliminate bonded contact, does ACP permit quadratic elements? Using quadratic elements in both systems would reduce the amount of mesh penetration. If you must use linear elements, making the elements smaller will reduce the penetration.
