I have a idea for a fuinjutsu Naruto fanfic.
In this fanfic Naruto runs across a random book on fuinjutsu in a training ground, he quickly finds out that he is able to understand fuinjutsu as easily as breathing, so he asks the hokage for more books on the subject, initially sceptical about giving Naruto the books on fuinjutsu due to how dangerous it is if done wrong, the sandaime decides to teach Naruto the kage bunshin no jutsu because it would allow Naruto to learn fuinjutsu through the memory transfer, without the danger of doing it. After finishing all the volumes of fuinjutsu including the uzumaki fuinjutsu that the hokage gave him after he finished the qualifications, Naruto decides to create a set of seals on a pair of contact lenses, making them fuse with his eyes and making them self cleaning and unbreakable, but the main thing these contacts gives him is the abilities of a fully developed 3 tomoe sharingan and the Byakugan (the ability to see in slow motion, heightened reflex's, the ability to copy any movement including ninjutsu and genjutsu, and the ability to see through walls, to great distances and people's chakra pathways and points) stuff like that.
So what do you all think of this idea? I know that it's a little bit out there but it should theoretically be possible because of the existence of space-time ninjutsu and fuinjutsu, and you cannot tell me that manipulating space and time is easier than giving yourself New abilities.
If anyone wants to use this idea, you are free to do so
