Quick thought

[Amaterasuice]

If Naruto represents the sage, could Sasuke represent both sons? No this does not mean by powers, it means by ideals.

Naruto: Will be able to perfectly balance love (will of fire) and power (Curse of Hatred) ideals together

While Sasuke will struggle to keep it balanced, as he wil either love too much or use power too much. Which he already struggles to do. But if he works really hard, he can keep it balanced. Just not as Naturally.

This is just a bonus question:

What if Naruto and Sasuke go these power ups?

Naruto:
Rinnegan on par with Sage's
Kurama back with both halves
Toad sage mode

Sasuke:
More powerful Elder son's eye
PS with Itachi's weapons
Dsm

Would they be somewhat even? Just asking.

I kinda want Naruto to stay without Kurama. That way all bijuu will be free in the end.

As far as representations all I know is that Naruto is Yang and Sasuke is Yin; Naruto is the Savior thats supposed to save the world, end the hatred, and lead the bijuu
