While the principle is correct, the setup for that would be difficult at best. The platform fulcrum points would have to be located within .100 of each other for it to function correctly. Then the center of the axles would also have to be centered in the platform between the fulcrum points to achieve the 50/50 ratio for the weight. Almost forgot. The platform would also need to be level, so fabrication of the fulcrum points would need to accommodate that also.
Most people would not get it right, and they would probably end up with a worse setup than if they just set the ride height with a tape measure.
