Head coach wants to trade w assistant

[bucky]

Coach A communicates to the referee that he no longer wishes to be the speaking, head coach and would like to transfer all authority, mid quarter, to his assistant. It has nothing to do with illness or any odd ,emergency situation. How do you recommend that this situation be handled by rule? How would any previous technicals, on either or both coaches, then be handled from a bookeeping standpoint? If it is allowed, what if the assistant (who is now the head coach) wants to have the situation revert BACK to what it originally was?

Any help/thoughts/advice would be greatly appreciated.
