Nest power connector with W2 wiring

I have a 5 wire thermostat cable so I can use the blue wire as a common wire but was wondering if I can use the blue wire to connect W2 (stage 2 heating as I have a 2 stage furnace) and use the nest power connector for the common wire? This will allow the nest to control the 2nd stage heating instead of the auto stage controled by the furnace (10 minutes) if only W1 is connected to the nest..
