I just imagined Jiraiya publicly declaring that he can no longer research and hence there will be no more Icha Icha books from now on due to which the whole male population of the world, doesn't matter who they were before came together. Rival merchants become friends, enemies out to kill each other joined hands and the 4 kages of the major villages together under one banner marched to Iwagakure to be able to free the source of their stress relief and this is how the whole Elemental Nation united.
Jiraya is still technically Naruto's godfather so maybe he can work in some visitation excuse to free himself from his current proximity to his 'wife'? As a side note given how much Naruto was able to eat as a kid in Canon I think he would get along great with the 'wife' as well. (Maybe have the above situation backfire and result in Naruto visiting the 'happy couple' instead, as a bid from the Earth politicians/ninjas to have their Earth country form ties with a jinchuriki?)
