When different p/p's still monopolize their enrollment advantages Thanksgiving weekend (particulary 1A-3A) I'd strongly disagree. The Yo-Yo factor of different p/p's taking advantage when another is SF'd up is, at best, and unforeseen, consequence of fixing the issue with ONLY the current SF system.
Trading one school with the p/p enrollment advantage for another is not (IMHO) the same as saying "mission accomplished".
I would remove ALL p/p's from 1A at a minimum.
