I don't think that can happen in the NBA. League is too strict with whatever goes inside the playing court.
What I do want to see though, is college hoop style crowd. I mean when I watch some college games, those student section get rowdy and entertaining to watch. I sometimes just watch a Duke game because of the Crazies. They are fun to watch and really intimidating for away teams.
It all depends on the fans and how crazy, yet inbounds they can get.
