That kind of assumes that movies bomb due to whitewashing in the first place.
They don't have a very good track record as of late.
Movies that have recently had whitewashing backlash: Prince of Persia, The Last Airbender, Exodus, Gods of Egypt, The Lone Ranger, Aloha, Pan, etc.
I'm struggling to think of a film with a recent whitewashing controversy that has done well at the box office. I think the only one that will prove to be successful in the foreseeable future is Doctor Strange, and that's because Marvel films are impervious to anything but success at this point.
Edit: Actually, Star Trek Into Darkness is probably an example of a film experiencing a whitewashing controversy that is successful.
