I like that idea, though again, it could have been any of TQoD that directed Killian towards Regina's tower to find Belle. The key here is that someone would first have to know that Belle was of some importance to Rumple. And even though most people knew that she was his servant, only a very few people would have discovered that she is also a weakness that can be exploited.

Going this route, though, I think it highly probably that it is, in fact, Maleficent, since whoever it is that points Killian towards Belle would not only have to know about Belle, but also have knowledge on Regina, and Maleficent is the best candidate to fit this category.
