There is an inbred nature of "racism as banter" in middle class communities, from universities to work places, so it's no surprise that the most middle class of sports would have the same problem and not even realise it has a problem. The reality is that no single organiser, sponsor, external consultant etc will be able to solve the problem. This is a societal issue and in the case of cricket, has to be solved by the players first and foremost. More non-white cricketers need to come forward and more white cricketers need to understand, admit and work on their wrong doings.
Until the latter happens the problem will never be solved.
