I don't have strong feelings about an in-season tourney that Adam Silver is trying to get through. It would be something else to add interest to the regular season, but adding games would affect the health of the players.
But this WNBA set up - all the teams have ten regular-season games that count for the in-season tourney - seems doable. The only added game would be for the two finalists.
This format doesn't seem like a bad idea at the least.
