This wouldn't work, or rather, it would work quite differently than the idea. This would just create a new level of middle managers in the house tasked with herding the foot soldiers. There are only so many hours that they can be in session or in committees, an ordinary representative will be lucky to get the microphone for a minute here and there. And there is no way the party's leadership can give them all individual time and attention. So there will naturally arise a management level or two between the leadership and the ordinary representatives to bridge this gap.
