No its not a bad idea cause the shippuden anime can go further like after shippuden how about a 4 year time skip naruto as a jonin so the series follow naruto as a jonin and sasuke as a jonin sakura as a chunin and they go on battles and missions threw out the series and in the end someone becomes hokage so that gives the plot of the series so that proves that theres just so many different aspecs you can do with the series
