Sure. There could be fanfics with this concept. Naruto is known for his own powerful abilities like the Rasengan and Sage Mode. But in the world of fanfiction, writers can bend the rules. Maybe in a story, Naruto gets the Susanoo as a result of a powerful curse or a gift from an ancient being. It would be really cool to see how he would use it in combination with his existing skills.
In a Chunin Exams - themed Naruto fanfiction involving Susanoo, Naruto might encounter an enemy who has a power similar to Susanoo. To counter it, he has to dig deep within himself and discovers an unexpected way to manifest a Susanoo - like defense or attack. This could completely change the dynamic of the exams and how others perceive him.
A possible plot could be that an ancient artifact is discovered during the Chunin Exams, and when Naruto touches it, he gains the ability to use Susanoo. However, this draws the attention of powerful enemies who want to take the artifact for themselves. Naruto must use his newfound power in the Chunin Exams battles to protect the artifact and prove himself worthy of this power. He also has to learn how to control it on the fly, as the battles in the exams are intense and unforgiving.
You can try looking on fanfic websites like FanFiction.net or Archive of Our Own (AO3). These platforms have a large collection of Naruto fanfics. Just use the search bar and type in 'Naruto has the Susanoo' and you might find some relevant stories.

Well, in such a fanfiction, it might start with Naruto being in a situation where he becomes Madara's pet. Maybe at first, Naruto is defiant but as time passes, he could start to understand Madara's motives in some strange way. Madara, on the other hand, might initially see Naruto as just a possession but gradually develop a sense of attachment. It could be a really strange and complex relationship that unfolds as the story progresses.
Madara would have to adapt to the different threats in RWBY, mainly the Grimm. In his world, he was used to fighting other shinobi and clans. The Grimm are a whole new type of enemy. However, his Sharingan would give him an advantage in detecting their movements. He might also try to find a way to use the Grimm's negative energy, similar to how he used negative emotions in his own world to fuel his power.
The information you provided is not detailed enough for me to give an accurate answer. However, according to your description, this novel might be The Clone Wars (The Clone Wars:A Story of the Clones). It was a novel about a world war between clones. The war started in Brazil.
Maybe an orphan from a non - Uchiha clan who has a special ability that Madara finds interesting. This character would be malleable and eager to learn from Madara, as they have no other real family or guidance. They could bring a fresh perspective to Madara's teachings.
