Best of luck to ACC if they see any kind of success in this adventure, in fact, it'll blow back in their face even if Jay shah is the president or not.
BCCI would simply argue that we don't take a single penny from Asia cup's revenue but subsidize the ACC.
BCCI is very poor in PR, and I am not sure how all this will end up. None of the "real" associate nations have a favorable opinion about the BCCI. Pakistan on the other hand, is held in high regard by many of the associate nations, including South Asian nations of Nepal and Maldives. Recently the PCB started Pakistan Junior League, in which one slot was reserved for the associate players. On the other hand the IPL is quite famous for filtering out players from associate nations. If the BCCI create unnecessary issues with Asia Cup, and thereby destroy the ACC funds, then I don't think that it will help with BCCI's reputation among the associates.
BCCI might be bad in PR or not, that's another discussion because when it comes to court cases in regard to any compensation claim. BCCI is ruthless as there you need facts, not PR and they focus on the latter.
BCCI only issue is with visiting Pakistan if this angle creates problems for ACC then I won't mind if all ACC members get together and kick out BCCI.
