I was thinking about an idea for a Naruto and Yellowstone crossover.
The idea was, Lee Dutton at an early age had sex with some random blonde at a bar and unknowingly father a child. And the girl, not ready to be a mother but didn't want to abort the pregnancy decided to give him up for adoption when the baby is born. In walks kushina, who is a single mother at the time, has established herself as a well respected doctor but never had time to date. Adopts the baby and names him Naruto. Some years later, she meets Minato who served in the US military and was stationed out in Japan, Naruto had a good childhood and everything else but always felt there was something missing in his life he was well aware of the fact that he was adopted but was still very much loved by his parents but still seeking that blood related connection. So when he turns 18 or 19 years old he heads to the US to Montana seeking out his father only to find out that his father had just died. Now he gets to meet the rest of his blood family. the Duttons.
For the pairing I was thinking it could be Naruto and Korra from (LOK). Primarily because she could pass off as native American, and she's hot
An alternate idea would be that Naruto is the son of Beth dutton and Rip wheeler, instead of going through with hysterectomy, Beth decides to go out of town for the duration of the pregnancy and give the baby up for adoption. But during the birthing process they were complications that arose that made it extremely hard for her to ever have children again.
