Sounds very plausible, but that is making Naruto sound more concrete and very single-minded. He obviously cares for more than just bringing Sasuke back, and love will possibly creep its way in there into one of his priorities. I mean, it's clear as day that Hinata loves him, even he can see that. I'll leave it to Kishi to decide (Obviously xd), but I would prefer he end up with someone by the end of the series.
Naruto has been almost selfishly selfless. In a debate I was having with another member, a while back, she (I think she was a she, at least... the internet is inherently ambiguous about these things) made the point that Naruto has developed a sort of complex where he still doesn't feel he deserves to be saved by another person. While I argue that Hinata cut through this quite effectively - it's still a part of his personality that will need some further addressing.
In a lot of ways - Naruto has been living for others and is yet to develop a strong sense of what he actually wants out of life, in the long run. Not that peace and protecting your friends isn't a good thing to live for - the problem is that you don't have anything to hold you over while things are peaceful. Naruto needs more to his personal ambition than just being hokage.
The normal paternal instincts will probably be a bit delayed in him, as he didn't have much in the way of a family to give him ideals of having one of his own, some day. No doubt, the instinct will eventually develop - it may just take a little longer than it does for most, and be a little bit of a cumbersome idea in his mind (as he doesn't have much experience with a family).
This is why I see Hinata kind of provoking that instinct in him - giving him the kind of support he's not really seen receiving from others (now that she actually has developed the ovaries to be direct with him). That's not to say that other friends (such as Sakura) have not supported him - but I think the entire context and nature of their support has been different from the kind of support and role that Hinata will begin to play in his life.
Because I really don't see her taking a depreciated role in his life from here on out. ... That doesn't mean that he is going to take a romantic interest in her (or that their interactions following the war will be romantic in nature) - but it does open up new ground for him to explore a type of relationship he's never had before.
