They can be integrated through their fighting styles. Saiyans are known for their brute strength and ability to quickly power up. In the Chunin Exams, this could be shown during the combat rounds.

One idea could be that Naruto forms an unexpected alliance with Anko during the Chunin Exams. Maybe they team up to uncover a hidden plot within the exams that threatens the safety of all the genin.

In a Chunin Exams fanfiction, Naruto and Temari could be paired in a team - up for a special mission within the exams. Their personalities would clash at first.

This would completely change the dynamic of the Chunin Exams as he would be a near - unbeatable force.
