Actually, that seems like worse advice than the thing you are trying to advise me against. I don't think there is a panel that works ideally with third-party DNS hosting. Most of them are a mess with no intention in mind to make our lives easier. I'm not scared of taking the custom path. Just in the last two months, I've discovered at least 5 huge inconsistencies and irregularities in cPanel's structure for which they now opened cases. That gives me the confidence to proceed and maybe show them how to do this.
