Not exactly, yes the romantic subplot would be resolved nicely but then what about afterwards?
If Kishi ended up choosing to show their children I don't doubt that he would screw it up somehow for example, by giving the girl super strenght even if she never trained before...things like that
If the story was really thought about, the Kids wouldn't be getting their own story and just leave it up to the imagination. This story was supposed to be about Naruto, not Naruto's kids. Again, when I say "an NS ending would be better" I am also implying that all the matters are resolved including, but not limited to the Hyuuga civil war to which Hinata could have been the one to end it and Neji seen as a hero because now that Naruto is no longer her priority she realizes that she didn't care enough for the more important stuff and learns a valuable lesson . Sasuke would still travel the world and actually have a reason to travel with Karin and maybe the other teammates. You could have suigetsu and such break off to somewhere else and have them come back as Sasuke and Karin only, but that something that can be hinted at later on.
You don't really have to explain every little details as given the right details people can fill in the blanks easily.
Think about this, if NS got together, you don't need to explain how or why they ended together. They were pretty much obvious. Just had to make them jump over the last hurdle. Which means you can spend the movie time or more manga pages actually talking about more important things and tying off any loose ends.
