A great fanfiction concept might be that Naruto somehow gains the Sharingan and Susanoo abilities. Maybe through some sort of experimental jutsu gone wrong (but in a good way). He then has to learn to control these new powers while still maintaining his own Sage Mode and Nine - Tails chakra. It would be interesting to see how he combines these different power sources to fight against new and old enemies.
In a fanfiction, what if Sasuke's Sharingan and Susanoo evolved in a completely unexpected way? For example, his Susanoo could gain the ability to fly and his Sharingan could see through different dimensions. This would put him in a whole new level of power and he would have to face the consequences of having such great power, like being hunted by new enemies who fear his capabilities.
