Blue lock X Tenkaichi

A while ago I saw that one of the questions on the data sheet was about who would develop better in the Sengoku period, this made me think of another manga that takes place in the Sengoku period (or later I'm not sure) Tenkaichi Nihon Saikyou Bugeisha Ketteisen in which for those who don't know, Oda Nobunaga, who in this reality unified all of Japan, organizes a tournament between martial artists to decide his successor since he is on the verge of death.

Then I wondered how it would be if they mixed both concepts, the blue lock and the Tenkaichi one, with Ego taking the place of Oda Nobunaga, only instead of being a tournament where the heir of Japan is decided, it is one to find the ultimate martial artist by gathering 300 martial artists from all over Japan and making them fight in a tournament to the death.

With this concept, what fighting styles do you think the characters would have in this reality?
