From a literal stand point; it will work with both fit and an electronics/sound point of view so long as you're trying to fit a humbucker to a spot where there is already a humbucker.
The question is whether or not the pick up will get you a sound that you will like. In the case of humbuckers, neck pickups tend to be a bit more mellow in tone to create that softer and more melodic vibe. Bridge humbuckers tend to be a but brighter and more aggressive/hot to give a more rock driven punch.
So it's a matter of what kind of sound you want out of a pick up. If your a metal player, it may not be the right choice but if you lean towards a more mellow fare, it may be the perfect choice.
