It seems that Kishi is building up him to be the FV since he plans on "tearing down the shinobi system and creating a new one" and "erasing the past" by killing Naruto. I believe Kishi also confirmed that NvS is going to happen which is unlikely until after Kaguya is dealt with.

But Sasuke doesn't have to be an enemy for the Naruto vs Sasuke fight. It could be the rival's fight instead. (In Shonen, the rival is usually a few steps ahead of the protagonist until they lose to the protagonist in which they then have to catch up to him).

Sasuke seems to have a political agenda, not a battle agenda. Naruto vs Sasuke doesn't necessarily mean "hero vs villain" or make Sasuke a "boss".
