3D-printing for prototype and later have the propeller milled

We were brainstorming about the use of 2 or 3 blades due to the size of the boat. Depending on the actual power needed to lift the hydrofoil out of the water we could reduce the amount of blades used on a counter rotating prop. Since the efficiency of the counter rotating prop design is more efficient, maybe it is possible to reduce the amount of blades from 6 to 4 on the shaft.
