What teams from the PCL stay, what teams get folded?
Dodgers and Giants stay in NYC. Maybe they share Shea or the Giants build a stadium in Hell's Kitchen or the Meadowlands...or maybe in pre-1965 race riots Newark?
Athletics stay in KC. Royals butterflied out of existence along with the Mariners and Mets. Sacramento, Portland and Salt Lake City have long, storied franchises.Charlie Finley doesn't buy the Athletics, maybe the Oaks instead. The A's stay in KC under the new ownership and aren't the dominant team in the 70s and 80s.
Milwaukee gets the Brewers a little earlier, and unlike the Pilots, the Brewers don't go insolvent. Selig never buys the Pilots on the cheap and thusly never becomes commissioner. Does realignment never happen as a consequence, or maybe with the three leagues merging, the MLB moves to an East-West format?
Imagine a northeast corridor division with the Red Sox, Yankees, Giants, Dodgers, Senators, and Phillies (although that would be even worse for me as a Phils fan).
Houston stays in the NL. With more teams voting , NL probably adopts the DH too.
If PCL stays independent like the AL and NL, what does the World Series look like?
