Wait I know how it could work out. After researching through her medical text books Tsunade learns of a set of seven sphere like ancient artifacts. When all seven of these "ninja sphere articfacts" are collected in the same place they can grant a person a wish of what ever they desire. With these artifacts Sasuke can be brought back to life. Unfortunatly these "sphere artifacts" are no longer on naruto's world. During a an ancient epic ninja battle they were thrown out into the stars.

So thus naruto and his friends embark on a new journey. Using Tsunandes rocket blast no jutsu naruto and company hurtle to the stars to begin a new adventure.
