Yeah that might happen, that's why I am saying many factors to consider:
- Akainu bloomed durung that fight which made him stronger decisively over the other admirals, therefore Zoro and Sanji might get one too, or Zoro gets one, Sanji and Jinbei 2v1 another one
- Akainu still isn't decisively stronger than other admirals, that would mean Luffy vs Akainu, Kidd might take one too (I liked the idea of Kidd metal scrap robots vs wrath of mother nature), Zoro vs another one or Zoro and Sanji together beat one. Jinbei then fights a zodiac VA.
I don't think Fuji is necessary going to fight any straw hat with the Dressrosa events. He might become a fleet admiral after Akainu imo. Maybe he gets defeated by Ryokugyu + Kizaru to make it a quick defeat.
