The youngsters are used to starting once a week in a six man rotation. Asking them to do something they have never done in their pro careers strikes me as a bad idea.
There's a reason for this. All minor league schedules now follow the same formula, 6 game series played Tuesday through Sunday either home or away against one opponent (Monday is a travel day). I'm guessing either all or almost all starting pitchers in the minors across all franchises follow that rotation.
I get why the minors went that route, it cuts down on travel costs, particularly at the AAA and to a lesser extent, the AA levels. The IL and PCL are very spread out.
