If Naruto gained the Sage's eyes, he'd have the full power of Hagoromo and the balance would shift in his favour. Once again Hagoromo would have chosen one over the other, which is the very thing that started his sons' feud. Agreed. I think it was deliberate, but also a callback to his original sons: one with extreme eye powers and the others without special powers but a strong body. In stead, he now split their powers evenly, Naruto who has immense power and Sasuke who has enormous utility (via the rinnegan).
