Your design sure looks strong! I think it'd be easy to have the 4 z steppers wired to work together in parallel and do Auto Bed Leveling the normal way by probing the 4 corners..
Having the bed actually level itself independantly in all 4 corners like i think you are suggesting would be more challenging.
Im looking into building a 3030 extrusion cube myself, im interested to see how this one turns out!
