Geographically, it might be half the state. But not numbers wise: only 14 of 53 Class 6 schools are in Region A (I know you realize this). Unless the VHSL goes to a true, statewide playoff system where all schools are ranked 1-X there is never going to be a way to fix the issue of clustered schools residing in our dense population areas. And we all know the wailing and gnashing of teeth that comes from every corner when someone has to travel more than 60-90 minutes for a playoff game. I acknowledge the increased costs and reduced gate from such a system but you have to pick your poison and choose between bad and worse.
Moving those schools from A to B would have essentially made it a situation where only two possible scenarios existed in Region A: 1) everyone gets in (unfair to other regions) or, 2) only 4 get in and have a bye week (again, unfair and much disliked by most coaches and fans).
