They could limit it to four teams. I'm no cricket player, but surely they could get in three games in two weeks?
Yes many nations with marginal cricket teams (perhaps including India?) would complain that they were left out, but similar unfairness happens in every Olympic discipline, e.g. when the top five in the world are from one nation that can only send one competitor.
The real popular cricket in india that I grew up playing is one tip catch out cricket. It can be played in minutes, with as few people as beach volleyball. Also if you hit the ball out of the playground or lose the ball, you are out!
But seriously -- do you think they'd play 20-20 matches to make it fit? That's still almost twice as long as a soccer^H^H^H^H^H^Hfootball match.
