I decided to start actually playing this save, and wanted to add more teams. So, two expansion drafts later and boom! 36 teams. This is what the North American Association looks like after expansion:
Also, since so many of these teams would have kept their city's minor league mascot/colors, I decided it made more sense to have the Kansas City Blues instead of the Royals. There's a set from the SFGiants58 concept
here.
MLB EXPANSION TEAMS:
AL East:
Florida Flamingos (in Tampa)
AL West:
Nashville Rock Cats
NL East:
Atlanta Firebirds
NL West:
New Orleans Crawdads
PCL EXPANSION TEAMS:
PCL North: Calgary Mounties (see below)
PCL South: Phoenix Crotalos (see above)
Several of these elevations require backfilling at AAA, and I've tinkered around with various minor teams and intend to eventually post those new alignments if anyone is interested. I stuck mostly to extant minor league teams but needed to make a few additions here and there.
