As another poster noted the Zeus requires cutouts/tunnels in the hull which would increase the cost to make the change and also change other aspects of the hull performance due to reduced buoyancy in the stern. However, in my opinion this is the correct way to do it.
If you are developing a hull just for this kind of drives, you can of course find solutions to the problems you describe. But you have to build it in full scale to test it out, which can be expensive if you are totally wrong...
