I don't see it happening. MLB owners hold onto tradition pretty ****ing hard.
Honestly I think it would be awesome.
8 divisions, each division winner is seeded into a best of 7 playoff to determine the World Series champion.
SPitballing assuming Portland.
SE mentioned already
North East - Toronto, Boston, New York, New York
Mid Atlantic - Philly, Pittsburgh, Washington, Baltimore
Midwest - Guardians, Reds, Tigers Cardinals
Other midwest - Twins, Brewers, Cubs, White Sox
South West - Diamondbacks, Rangers, Vegas, Astros
California - The 4 teams from cali
Northwest - Royals (sorry Royals, you're odd man out) Mariners, Rockies, Portland (also would work for Salt Lake City)
