[With apologies to Inigo Montoya] I don'a think that word means'a what you think it means.
Non-backdriveable means that torque applied to the output shaft will encounter sufficient friction that it will not turn the motor (with no voltage applied to the motor). It does NOT mean that the system cannot be driven in reverse from the motors.

While I have obviously not spent as much time with your design as you have, I don't see this at all. As I'm picturing the fasteners, this would be a matter of switching the threads from the chassis to the module, with no net difficulty in assembly, other than the requirement to hold the module up as the machine screws are being threaded. If a few alignment tools were in place, even this could be accomplished with gravity.
