It simply isn't doable in Buzzerbeater's two league games per week format. Not without major changes to the schedule and the way game shape works during the play-offs. It doesn't add much to the play-offs either, as even with the finals being Bo3, whoever takes game 1 usually takes the series.
I would sooner argue in favour of a single game, neutral venue finals, and the scrapping of the all-star break, to bring the season down to 13 weeks and speed up the game.
