There's nothing really wrong with the current playoff format, but a bit of research indicates that at one time the east division would do a two-game total points series for the East Final and the West did a best-of-three series for the Final. The season could start earlier to compensate. You'd probably want the same format for both divisions though. You could extend the playoffs an extra week and have an earlier start to the season. The extra home date could make more money.
Just an idea, for the sake of debate.
The thing I wouldn't like about two-game total points series would be how teams would have to run up the score.
