Interestingly, the 1939 Citroen 2CV 4-door salon prototype weighed in at just 400 kg with its magnesium axle arms and lightweight aluminium bodywork. Later additions of an electrical starter, a passenger compartment heater, and a steel bodywork and chassis increased the weight a lot. On an expensive three-wheeler and with use of modern materials, the 410 kg dry weight limit should certainly be possible.
