Naruto And Fairytail Crossover Challenge

(Im bad at writing stories so if someone wants to take the idea then let me know so I can read it please.) Naruto and wendy are fraternal twins and are supposed to be sent through the flying thunder god technique to send them to grandini the sky dragon to protect them from the nine tails but during the transport the celestial dragon (insert name here) senses great potential in them ane tries to take them both to train in the dragon slaying art but is only able to get naruto before the rift closes and cant get wendy and can't go after her because she can't contact other dragons because of the disease she has that kills dragons within 7 years and only trains naruto. (Make it so when they meet they give each other bits of their powers so naruto has celestial-sky dragon slayer magic and wendy has it too. I don't care about pairing and they act similar)takes place in the fairytail world. Thank you for your time.
