We're not sure even where he is, much less if you can refight these teams.
He's basically the only trainer we don't know about fighting so far as I know.
edit: Oh right there is one other fight with N. In the post game sidequest to get Zekrom/Reshiram & then Kyurem, you fight his level 70 Zekrom/Reshiram
