Bracing off extended wing posts was tried at regular intervals. It never seemed to work as well as a central cabane.
The wings were bigger and lighter, so they benefited from more support. Also, the larger airplanes didn't need the variable wash that keeps our smaller planes from torquing in or stalling at launch.
Compression ribs at the dihedral breaks / bracing points was vital. Without them the ribs would bend, the bracing would go slack, and the wing was at risk of folding.
