From asking around, and research, it sounds like Klipper might run into issues with the dual MCU setup I'd need. This is becuase boards like the RPi (and I assume the Orange Pi) are not realtime.  The main concern is the dual ZM (main z gantry) axis, which ideally should move at the same time.

This is what I'm currently planning:

  1. Octopus Pro
    1. X1
    2. Y1
    3. ZM
    4. ZM
    5. W1
    6. V1
    7. E1
    8. S1
  2. Octopus Pro
    1. X2
    2. Y2
    3. Z1
    4. Z2
    5. W2
    6. V2
    7. E2
    8. S2

Yes, there are a few limitations in klipper with multi-mcu setups. I know that paired motors are supposed to be on the same MCU. I believe that it's recommended for limit switches to sit on the same MCU as the motors they control, as well. ie, your X end stop should be on the same mcu as your X motor(s). You might want to double check that one, but I'm pretty sure.
