As far as it being interesting it's really hard to make it as interesting as the actual series. Unless they made a gaiden or something along the lines of adding to fights and such.
I already said something about just making fights an episode longer [main fights that would have added another 3 episodes.] Another Gaiden or Two. [4 More episodes] and then a few other things like revisting what is under kakashi's mask, what is ACTUALLY in the ramen ect. just silly things which would have added another 2 or 3 episodes. [Seperate them so they don't take up a FULL episode but just a break from the episode itself.] Or do something like a playful matchup between Gai and Kakashi, or follow along what happens with gaara or a different squad. I wouldn't mind seeing Shikamaru's squad do another mission, or following along with konohamaru. It'd be better then ANY of the filler arcs we've watched.
There IS infact MORE to this world then what Naruto experiences. ;/
