Apparently, according to the novel, Naruto and Shikamaru ended up just redoing them. Nice spot for SP to start a Boruto anime instead of making crummy fillers. But what would have happened if they had continued in the movie?
Shikadai vs. Boruto (Shikadai won)
Sarada vs. Shinki
Mitsuki vs. Inojin
Mitsuki probably wins due to being a slightly more relevant character than Inojin. Plus, they wouldn't have both Inojin and Shikadai in the final. They would team up on either Sarada or Shinki. There is no mention of a rivalry in their friendship, so there would be no one-on-one fight.
Shinki then probably beats Sarada. This way we don't have two Team Konohamaru members in the final.
Shinki vs. Shikadai vs Mitsuki. Who knows? Shinki is a Gaara/Kankuro hybrid. I can see him having a beef with Shikadai because of the Kazekage bloodline and being Gaara's nephew. Shikadai might start breaking out wind jutsu. Mitsuki probably waits back and fights the winner.
