seems like baseball before inter-league play was a thing. If you're so desperate for a season, that you decide to go ahead with biodome ball, just change it from NL and AL to Florida and Arizona for a year- the season will already have an enormous asterisk, does one more really matter?
Baseball before interleague play was a thing, but they didn't have the cocked-up schedules that would result this year. Prior to expansion, for example, when you had the two single tables of eight teams each, you played the other seven teams in your league 22 times each, 11 at home and 11 on the road, for a 154-game season. That was modified slightly in the 1960s, and then the 1969 expansion altered things due to divisional play. But you still played everyone in your division. The idea of having a single table where you don't play everyone at least once makes no sense at all because there's no valid statistical basis for playoff qualification—that is, it's surely not fair if one team gets to play Baltimore 25 times (54–108 last year) while another team has to face the Yankees 25 times (103–59 last year).
The idea of having Cactus and Grapefruit makes more sense. I've never understood, for example, why the Washington Post prints spring training standings divided into "National" and "American"; some other news outlets do use "Cactus" and "Grapefruit" because that's more logical. The Nationals don't play Los Angeles NL in spring training, for example, since the latter left Vero Beach.
