That's sound like a good option, every board should stand up against BCCI and force ICC to ban India from the international cricket, so what if BCCI generates 70% of revenue and brings more on the table. I am sure all cricket boards and ICC won't mind reduction of funds once BCCI gets kicked out from the Int community. 
The ICC needs BCCI, as much as the BCCI needs ICC. But that doesn't mean that the BCCI should be given lion's share of ICC revenues, at a time when some of the smaller boards are facing bankruptcy. None of the other sports bodies such as FIFA or FIH follows a similar model. They divide the revenues equally, without thinking about from where the revenues are originating.
