That's exactly where I would end it too. It's quite logical for a number of reasons.
It's ending the second movie that worries me. I'm afraid they'll do it after the death of Smaug, but I think there are serious problems with that. The book (like the LOTR movies) have false ending problems. And audience members who aren't familiar with the story will have been told this is the quest to kill a dragon. They'd be kind of confused when there's a third movie and the dragon is dead.
