I would be okay with this lineup, but not necessarily for 16 minutes per game...that's quite a lot. When Washington is averaging 16 minutes per game currently.
CJ isn't as much of a TO machine as people think he is. He is averaging 2.7 TO per game with a 1.2 Ast/TO ratio...while not great, he isn't the sole cause of the TO in a game. Factor in that when he is in the game, he is touching the ball probably 2-3 times more often than any of the other players(the role of a PG), factor that in and his TO would be .9-1.3 per game, which only Washington is lower at 1.18 per game and he is playing half the minutes CJ is.
Kaleb has 2.25 per game, Lu is 1.5, Dre is 1.7, Washington is 1.18 and Woods is 1.37.
Not saying CJ doesn't turn the ball over, just saying he isn't the TO machine that everyone says he is.
I would love to see Ahrens get some more minutes, but I also trust that what Holtmann sees in practice everyday has him not yet ready to give those advance minutes to Ahrens. I believe when the time is right, it will happen.
