Id love J. Lewis. He runs with a lot of heart like Barber and would have a lot in the tank sharing carries with him. The only thing is, ego might come into play over who starts and gets more carries and to my knowledge, he likes Cleveland anyway so I dont see him leaving for half the production.
Turner seems like he'd be a good contrast to Barber's style to keep the defense switching up their style and like the thread starter said, he's fresh.
