Mechanics would change for sure, but from my experience once you get to the point that you'd be adding a referee or two a short pregame discussion would take care of the cohesiveness issues. Beyond that, you'd probably be able to know if you're the 6th or 7th official with around two weeks notice. You should be professional enough to take the time to speak with the crew you'd be joining.
I'm on both sides as a coach and official, I have to be honest that the officiating on the High school level is not up to the level it supposed to be. But because there is a shortage of officials in Illinois, the level of competency of officials is not very high. Officials should be made to handle lower level games (JV, frosh-soph, elementary) for a few years before they are allowed to do varsity games.
Maybe a 6 person crew beginning second round or quarterfinals. Definitely not the first round. There aren't enough officials ready for it in the opening and first rounds. Yes, I realize there are crews covering more games during the regular season, but some of those officials work college games on Saturdays rather than high school playoffs.
