Story idea: Minato and Kushina are transported to Windmill Village after sealing the Kyuubi. 17 years later, after the 4th Ninja war, Naruto arrives in the same world and joins the Straw Hat pirates. Starts right after Romance Dawn arc

Genin age is 14 not 12

Challenge story backstory summary:
After the Kyuubi sealing, Minato and Kushina are transported the East Blue to Windmill Village (luffy's hometown). They stay there for 7 - 10 years, making friends with the villagers, especially Luffy and Ace (Whether they raise Luffy and Ace or are just a major part of their lives are up to you). They train them in speed and hand to hand combat, raising them almost like their children, all the time remembering Naruto, hoping he is doing ok. They tell Luffy and Ace about Naruto, Luffy and Ace hope to meet him one day.
By the time Luffy leaves (at 17), he is stronger and quicker.
Minato and Kushina leave the village and explore, along the way they come across Cocoyashi and make friends with Nami and Nojiko, travelling to the grand line, meeting Nico Robin and befriending her and looking after her for some time (1-3 years). Eventually Minato joins the Whitebeard pirates making a name for himself (Yellow Flash as usual) and makes a name for himself with the World Government and Kushina joins the revolutionaries, also becoming well known. Minato and Kushina learn Naruto has arrives in the O.P world through the toads.

Meanwhile, Naruto has a troubled childhood, being beaten and neglected by only the civilian population and certain shinobi. The majority of the shinobi respect him, he also makes friends with Anko, Kakashi, Asuma and the rookie nine minus Sasuke and Sakura. Sasuke is not a massive jerk (he doesnt expect everything to be given to him, he still thinks he is better then everyone, Sakura is still a sasuke fan girl, improves after Chunin exams). Teams remain the same (Naruto is stronger as he has had actual training by Asuma, Kakashi and Anko). Canon until chunin exams (Haku survives and comes back to the leaf, becomes Naruto's girlfriend)
Chunin exams are normal for the most part, Sasuke still gets curse seal. Fights are the same (except Naruto has an easier time). Hokage still dies after battle with snakey, Naruto Gaara fight is normal.
Tsunade retrieval arc is canon. Naruto becomes Chunin and learns of parents, gets parents estate and jutsu library. Sasuke leaves the village, Naruto defeats him however Kabuto turns up and incapicates Naruto then takes Sasuke back to Snakey. Civilian council are upset however Shinobi are not, Naruto leaves with Pervy sage for 2 years (gets extremely strong, low level jounin. learning primarily Wind and Lightening techniques).
Shippuden is canon up to the war (Naruto also meets his parents the same way as they believed that they would die).
During the Juubi/Madara fight, Haku sacrifices herself to save Naruto, Naruto gains Rinnegan, wins then becomes the hero of the elemental nations. Sasuke helps the allied shinobi forces then returns to the village.
Even though everyone is happy, Naruto is depressed. Back at the village 3 days after, he recieves a message through the toads from an anomous person saying that he is not alone (from Minato and Kushina).
4 days later he meets Kuma who asks Naruto if he wants to go on a trip, Naruto replies he want to get away from the village, Kuma tells him to pack all his stuff within 2 hours (Naruto packs all jutsu scrolls and weapons including Hirashin Kunai and Mothers blade (name optional) Kuma sends Naruto to Orange Town days before Nami, Luffy and Zoro arrive. Naruto help Luffy with Buggy and then joins his crew. Sakura watches as Naruto disappears and is scared at first. Konoha are upset about his disappearance but communication via the toads, they realize that his is safe and where he wants to be at present. (Toads can travel cross universe's cause why not)

All of the above is backstory for the sake of modeling Naruto's character and his attitude towards certain topics (Choppers friendship issues etc).
