The only thing stopping the PAHL teams from doing it are the PAHL teams. For starters, if the coach doesn't want to do it then it won't happen. The organization also has to give them extra ice slots for practice and independent games. That may not be possible. If it is possible then you got to pay more. Does everyone want to pay more? Not always the case. Sometimes, parents are happy to play AA and a couple of tournaments. And lastly, they need prime practice slots since kids are likely traveling some distance to get there. If you are having a high level AA team your team probably isn't home grown. All of this makes the other teams in the organization mad and jealous.
