If it's Blackbeard you were talking about, he was not considered one of the Yonkou at the time of Bonney's arrest, right? Actually, I think encounter with a Yonko, whether that certain Yonko at the time of their fight is already as a Yonko or not, is one thing the World Government considers when choosing a new Shichibukai because it gives the Marines the edge of "battle experience" in balancing the three great powers.
