I think it makes sense for NorCal to have fewer teams in the Open and maybe Division I. Even if the Central Section is moved north, there are still many more schools in Southern California than in Northern California. By bumping a couple teams down from each division, it gives the NorCal teams a fairer shake.
The other way to do it would be to take half the schools in the state and pick a Regional bracket from that half, and another one from the other half. But then we'd have a SLO team driving to Yreka for a first-round game ...
