Respectfully, there are a number of holes in your argument. First off, this is Peewee A. National championships and rankings don't fit into this in any way at least on the Boys teams. Peewee A can win SCAHA and/or go to states and that is it. With 22 teams in Peewee A, scheduling is a logistical issue, and with that many teams there are already significant issues with strength of schedule that can effect whether or not a team makes the playoffs. If it's anything like last year the last few spots will come down to a game or 2.
It seems you want the girls to have their cake and eat it too, being able to contend in SCAHA and play in the girls division in tournaments and nationally. That is great for them, and I wish them all the luck in the world, but it doesn't mean that the rest of SCAHA should be re-arranged to cater to them, and it IS a slippery slope, because other teams, particularly at the top of the division, may find it desirable to push their limits by seeking out tournament opportunities during the standard SCAHA schedule as well. It certainly was that way in Squirt A a few years ago. Girls have plenty of options at 12u. They can play on regular boys teams, they can play for a girls team, or in some cases they can play for both.
I don't see how this is important to the state of Socal hockey at this age. This is a development age group, and nobody is recruiting or taking anything too seriously for 12 year olds that are playing no-check. The entire issue is sorted at 14u when things begin to get serious, and you don't see too many girls choosing to play full check travel hockey at 14u.
