BCCI had already made an official proposal to play Pakistan's 'home' series in India, and allow PCB to take the profits after reimbursing the costs. PCB refused that offer. As of now, I believe that offer is not going to be on the table. But with some quiet diplomacy by the PCB, this is probably the best way out of the mess for them. Not right away, but a couple of years from now. This way, the PCB has something to offer the BCCI as well. And they will need to do that, in order to mend fences. But first, they will need to do the diplomatic work, make loud and public noises about respecting the BCCI to undo the damage done.
