I think a small step would be to do away with divisions, have every team in each league play eachother an equal number of times and have one series against a team from the other league. Take the top 4 or 5 teams from each league and run the playoffs
twins would play 7 games against the other 14 AL teams (4 and 3 game series) for a total of 98 games. Then you could play 3 or 4 games against every NL team (45 games or 60 games)
