Naruto could use Escanor's power to boost his physical attacks. For instance, when he throws a punch, it could be surrounded by the sun's energy, making it more powerful.
The plot could revolve around a villain who is immune to Naruto's normal attacks but is vulnerable to Escanor's power. So Naruto has to fully embrace this new power source. Along the way, he might meet characters from Escanor's world who help him understand the power better. There could be a lot of action scenes where Naruto uses the power in creative ways, like using Escanor's 'Rhitta' weapon in combination with his kunai. And there could be a sub - plot about Naruto's friends being a bit jealous or worried about this new power he has.
In such a fanfiction, it might be that the powers combine in an unexpected way. Escanor's power is often related to his pride and his 'sun' - like strength. Naruto could learn to use this power in a way that combines with his own chakra system. Perhaps he uses the pride aspect to boost his confidence even more in battle, and the physical strength to enhance his taijutsu. It could also lead to some interesting character development as Naruto has to deal with this new, more egotistical side of his power.
It could be really exciting. Maybe Naruto gets some of Escanor's power of the sun. He could use it in battles against tough enemies like Madara. For example, he might be able to increase his strength during the day like Escanor does with his 'Sunrise' form, and become almost unbeatable.
Naruto would become more confident. With Escanor's power, he'd have a new level of strength that he didn't have before. He might be less impulsive in battles because he has such a powerful ace up his sleeve. For example, instead of rushing head - on all the time, he'd calculate his moves better, knowing he can unleash Escanor's power when needed.
I'm not entirely sure if there is a specific 'naruto is escanor fanfic' out there. It depends on the creativity of the fanfic writing community. Some writers might be interested in exploring how Naruto's personality and abilities would interact with Escanor's, perhaps in a scenario where they meet in a different dimension or something. But you'll have to do some searching on the major fanfic platforms to be certain.
