I wonder what the range and battery weight is? This could make good sense for short flights. Doing this with sea planes also makes sense; for conventional aircraft, the airport might be a bottleneck which could be a safety concern if the plane is powered by a battery without enough spare capacity to wait around to land. Being able to land anywhere with smooth water mitigates that risk.
