Motor mapping question for 12 motor system

Hi everyone,

I’m wondering what the best approach would be towards getting a system like this set up.

What would be the best / easiest way to do this?
In theory sending one PWM out and splitting it into the separate ESC’s for the motor could work. Even though the arm of moment for each motor is different so the effectiveness of the equal force on the moment that is created will be different the net result should move the drone where it should be. Or am I making some thought error’s here?

Looking forward to some ideas before I start working on a similar build.
