I will add one thing to the discussion, as a courtesy, new managers have always been allowed to switch their stadium or trade the right to switch to another manger for their stadium.
This would always be part of any stadium rules.
PS there is nothing simple about keeping track of stadium swaps in your suggestions. Your ideas while well thought out would be a major book keeping PITA. I would suggest making the ability to switch every year or not at all. Trying to keep track of when everyone switched when we average one owner drop out every year, is more book keeping than I would really want.
K.I.S.S.
If you don't know what that means let me know.

That said, if your proposal is what the league wants, then that's what we'll do.
