If your frame meets the specifications of the end customer, there's no circumvention. Whether that's enough for your bumpers to have a safe home is a separate topic, but WCD with bumpers is a solved problem (generally, by adding a bar across the sides in some compliant manner to define the frame perimeter and provide the bumpers a good home).
