Let's not get silly here.
Wasn't this like the whole point of my previous post? Basically there is no fool proof way to determine in which division each team should begin. Therefore it'd be great not to have too many divisions as it can be a real route of suffering for those who are new but good, or have developed a lot during the off-season.
This could work. I think we should also increase the amount of teams being relegated to Lite and promoted to Pro, no matter if we extend the Pro division or not. This way we wouldn't have Pro level teams being stuck in Lite because there are too many of them competing against each other.
Especially by extending Pro to 48 we could even do something as radical as promoting and relegating 12 teams in a season, which is 1/4 of the division, just like 4/16 in Elite. You could have 1 or 2 teams with least points being relegated automatically, then let the rest play a 7 game series for the promotion/relegation. That way we would know for sure who belongs to Pro and who doesn't. This way we could also throw all the new teams into Lite (if we want to implement a rule like that) and they would get promoted for sure after their first season if they are top-Pro/Elite -caliber.
