hehe, well I won't underestimate Naruto, he can learn anything when he is motivated and having Sasuke around showcasing his abilities would probably motivate Naruto to achieve the same level.
Their fighting styles would be different than they are now in manga though because Sasuke style would revolve around his lightning manipulation (can train with Kakashi), fire jutsus (self taught), maybe hawk summons (self taught) and using sharingan genjutsu (self taught and Kakashi). Naruto's style would be to counter Sasuke's style so Naruto would also be a different fighter.
Result of this is maybe Naruto would become more cunning and aware of opponent ability in combat as he would constantly have to adapt to Sasuke's style and counter it so he would trade the power he has now for increase in intelligent style of fighting.
