Move Memphis east instead of Minn.
Just ditch East and West and make four 8-team conferences. Play 2 times with out-of-conference teams and 6 times with in-conference teams for a total of 90 games.
I like the idea of four 8-team conferences. It makes a lot more sense. I'd ease up on the number of games though. I understand it's unlikely to happen but it'd improve the quality on the floor imo. 2 times against out of conference teams and 4 against conference teams = 76 games. You drop 6 games in the calendar which could give a longer All-Star break or an extended training camp.
Assuming Seattle and St Louis the conferences could be:
West: Seattle, Portland, Sacramento, Golden State, Utah, LAC, LAL and Suns
Mid-West: Denver, OKC, Dallas, Memphis, San Antonio, Houston, New Orleans, Atlanta
North: Minnesota, Milwaukee, Chicago, Detroit, Toronto, Cleveland, Indiana, St Louis
East: Boston, New York, Brooklyn, Philly, Washington, Charlotte, Orlando, Miami
You can flex it around and put the Southern teams together and then a central division from Denver to Chicago too
