The plot of a Naruto turns into Sakura fanfiction could involve Naruto experiencing Sakura's emotions more directly. He might feel the pressure she has always felt to keep up with Naruto and Sasuke.

This would force him to fully embrace Sakura's skills and personality. He could end up using her intelligence and strategic thinking in ways he never thought possible, which would not only be a growth for the 'Naruto - in - Sakura' character but also an interesting exploration of Sakura's potential.
One possible plot twist could be that Naruto, while in his Kyubi form, loses control completely and starts to attack his friends.
