You know, it could work so easily if-

During the High School season (which in SC is essentially Feb.-May) the players playing HS were exclusive to HS during the week and whatever tournaments or games occurred on the few weekends that it happens. They could still train with their Clubs on off HS weekends.

And during the Club season, which can be the rest of the calendar the Club players are exclusive to Club.

But, the Clubs will not accept this. As said before on this board, Club wants all your time and as much of your money as possible.
