I would end the manga after the war, and a year or two later, continue the story line with naruto who is a hokage now, with two sons, the older one is a very talented jounin who is helping his father obtain peace, and the othe kid is just a kid, still like 10 years old who dreams to become epic like his brother. Somehow orochimaru seals a bijuu inside the older son, without him, or anyone noticing, and the older kid finds out about the bijuu a year later,and tries to control him with the help of is father and killer bee. Then orochimaru does something in the process of controlling the bijuu, and kills the older son. Whatever happens later has nothing to do with oro. A week before that happens, he finds out about something strange in his younger sons' DNA. He figueres out that he, for some reason has a KKG that allows him to control and obtain any KKG, including wood release, and rinnegan...he still though doesnt know how to control, and never will. The story infolds after words, its really long in my head.
