Denon X7200 has recently released a unified speaker placement approach for Atmos /DTS X and Auro 3D speaker placement. With that you can make 7.1.4 speaker palcment common for all the above audio formats .You don't require ceiling speakers for atmos .Only the 4 height speakers kept above the fronts and rear surround is enough.You can check out that .I think it will be simplified system for you.Check this link for more info.
