You're right about it sounding far-fetched, but so do a lot of things that ultimately prove to be true in this series. I've always been open to the idea of any Haoshoku user on the crew, but I always thought it'd be JUST Zoro, or Zoro AND Sanji, but not Sanji unlocking it first. But you're absolutely right, Oda has proven time and time again this series that a true King is the one who actually cares for and loves his subjects, and treats royalty as a privelege rather than a birthright. The storyline with the Vinsmokes is probably the first this series that truly addresses a royal family in power abusing it like this. My never-gonna-happen wish would be that they try to sick the entire Germa 66 army on Sanji, and he one-shots them all with a wave of Haoshoku. I doubt they have 50,000 soldiers, so it wouldn't be outshining Luffy.
