There is a nice idea posted by 'New Universe Returns' where a post-4th world war/post pain arc Naruto gets transported to Shantae's home islands where risky boots is starting an attack. The Narujtoverse and the Shantaeverse are in the same dimension but separated by a 'veil' that cant be broken so the shinobi world is completely cut off from the rest of the world. Naturally there are no lemons and surprisingly no fart jokes and running gags. He even thinks that is can either be a naru-shantae or a naru-harem with the shantaeverse girls.
To New Universe Returns if you do this fanfic I will probably favorite it and keep track of it so please tell me if you plan on it and when the first chapter is up if/when that happens.
Thank you
