What's a Naruto Fan Theory or Headcanon that you wish was true?

For me it would be these:

1. Before it was revealed that Itachi was a double agent/loyal ninja to the Leaf who massacred his clan to protect the village on the orders of Danzo, I saw someone theorize that Itachi wasn't evil, but rather someone who genuinely snapped due to the psychological horror and stress of being a child soldier, and killed his family in a manic episode after all the warning signs of his mental state were ignored. I personally really dug that theory and kind of wish it were true since I want the trauma of child soldiers were explored more.

2. That Sakura is related to Rin. I've seen a few stories where Sakura's mother Mebuki is Rin's older sister that I really enjoyed. I think in hindsight with her becoming a medic-nin and kind of being on the outs of her team, it would have given her a better plot connection to the story in a way without taking away her ordinariness by making her part of an OP clan (since I think Rin's civilian? idk never saw anything in canon or in interviews), that she was inspired by tales of her aunt to become a shinobi and had an interest in medical ninjutsu before becoming Tsunade's apprentice because of her. Also kind of makes Kakashi always stepping in to save her have another dimension to it (plus, we can psychologically scar Kakashi even more with his genins reminding him further of his dead team! :D)

3. That Teuchi was one of Minato's teammates in the genin days, and recognized Naruto was his son and gave him free ramen to eat as a way to honor his former teammate by taking care of his son the only way he could. I saw that floating around based on the image of Minato's teammates, since one of them looked like a younger version on Teuchi. I just thought it was kind of cute.
