Here's a Plan that would satisfy a lot of different dynamics, egos, and billionaire cravings.
Leave all the current teams where they are. Expand the league globally by having a world conference along with the conferences they already have. Put an expansion team in LA that would play a London team, Mexico City, Beijing, etc.
The winner from that conference goes to the playoffs same as all the others.
You LA fans are the ones who keep calling yourselves an international city, this would address that. The biggest problem I see with this idea is that the owners other plans are too far along to stop.
