Oh, there are definitely ways of making it work, no doubt, just like any other character arrangement and plot development. Again the issue is just "why isn't this more common" and, as was said, it's a relationship that requires the development of two characters (in addition to the protagonist) to pull off effectively. So it's not necessarily the most... "efficient" character relationships to develop in a story, I guess. But it can definitely happen, and most of the ones I can think of where it was done, it was done to interesting effect.
