I can't say a Naruto game would ever draw my interest again, due to how low my opinion is of the source material, but I think adding avatars to established universes is something that can definitely have potential. It was done to an extent with Bleach: 3rd Phantom, and I'd be excited to see it happen with One Piece and Fairy Tail, along with a few other long running shonen series I follow. With games based on existing IPs, I'm much more interested in exploring new facets to the established universe than simply seeing the same story content again that I've already read/watched.
Though that's just my preference...but this definitely seems like something fans of the Naruto universe can enjoy.
