Dolby Atmos 5.1.4 Hybrid/Overhead setup

[EJC]

Hi all need some assistance/advice with the above setup.
Currently have a 5.1.2 overhead setup with the tops being in a “middle” position as shown in the diagram (red circles). Thinking of adding front up-firing modules to my current setup. The question is would I be able to keep the overhead speakers in the same position or would they have to be moved behind the MLP as per the dolby Atmos diagram? AND would it make a substantial difference to the overall Atmos sound?
