You thought it was idiotic because it would never happen, or because it would not be a good idea?
I fail to see why it would not be a good idea if it could happen. Certainly it would be good for the UConn women's basketball team, and every player would applaud if they could play an ACC conference schedule rather than the AAC schedule. So would all of us fans. So would the fans of many other ACC teams, who would like to see UConn play on their campus on a somewhat regular basis.
I also don't immediately grasp why there would be such opposition to the idea. Are you saying that the UConn administration would not want to join the ACC for a single sport, and would hold out until it was accepted for all sports? Why would they not take what they could get, especially if the revenue impact is minimal? Or are you saying that the ACC schools would oppose UConn entering for WCBB? Why -- because UConn would win too many games? That might concern the other WCBB coaches, but why should it concern the administrations of those schools? They would see revenue, TV dollars, media attention, and (if they are rational) think it is all good.
I would think there is a deal to be made here if the parties are rational and are willing to look at it.
