This depends on the situation and the type of wind shear. You would have to be absolutely certain at that altitude to go back to initiating a normal go-around procedure. Think of it this way:
The procedure is designed to give you maximum angle of climb by putting you close to the maximum AoA. If you change the configuration you're changing the centre of pressure, the coefficient of lift and the centre of gravity. If the wind shear returns as you reconfigure you could stall the wing. Personally, I would leave it to a higher altitude, but I wasn't there to see what the was shear was like. Safest option usually works out though, even with a minor flap overspeed.
