That will work for a 4 cylinder that has 2 opposing cylinders to counteract the imbalance, but because of the 120° crank angle of a 6 cylinder crank, it takes 3 cylinders to counteract the imbalance because they never have another cylinder 180° away to oppose the weight difference. So you will need(2)sets of 3 R&P, not(3)sets of 2 R&P to do that.
