Blackbeard could also be a main antagonist. He has his own ambitions for power and the One Piece. With Luffy getting stronger under Dragon's training, Blackbeard would view Luffy as a direct competitor. Their paths are bound to cross, and Blackbeard would not want Luffy to achieve his goals before he does.
The World Government could still be the main antagonists. Since Luffy is getting stronger under Mihawk's training, they would see him as an even greater threat. They might send their top agents, like the Cipher Pol units, to try and stop Luffy's progress.
Perhaps Dragon would also introduce Luffy to some new allies or inform him about the greater political and power struggles in the world of One Piece. This would give Luffy a broader perspective and help him understand the significance of his actions. He might learn about the true nature of the World Government and how to better fight against it, not just for the sake of his crew and friends, but for the freedom of the entire world.
One possible plot could be that Luffy, realizing he needs to become stronger in a different way, seeks out Mihawk. Mihawk, seeing potential in Luffy, decides to train him. Luffy would have to endure intense swordsmanship training, which is quite different from his usual combat style. This would also lead to some interesting character development as he struggles to adapt to Mihawk's strict training regime.
