naruto said that he would change the hyuuga rules when he becomes hokage during his fight with neji^^
naruto said that but he was young and dumb then you cant just become hokage and say "ok i know you have done things a certain way for generations but srry i think it would be beter this way so im going to change the structure of your clan and how things work" cmon dude thats not how its going to happen i do think naruto could indirectly change the hugya clan through his actions they may come to light but he cant just change it
