Yes, they should have done this instead of screwing with the gearing on the transmission. In doing this, they took a car that was doing decent on gas and made it bad again while making it harder for Dodge to win the 0-60 runs as it now has to be shifted.
Fiat needs to pay careful attention to the mistakes made during the Daimler years and learn that if they try to protect their high end cars from Dodge beating them, they are shooting themselves in the foot as Chevrolet will not hold back and is probably on the verge of beating their high end cars too. If Dodge does a better job with simpler technology, don't punish success, LEARN FROM IT!!!
