I'm adding a second set of Atmos / height speakers to our 7.2.4 setup, which already has one set of in-ceiling speakers. This will replace a set of upward firing speakers. I'm debating between another pair of in-ceiling speakers versus a pair of speakers firing diagonally from the front wall - ceiling interface (such as the Klipsch RP-500SA).
This doc gives a sense of the room layout (which is far from ideal). Don't treat the system components as final - this is in flux.
