Its nice to see others also is pondering on the idea of a variable pitch multirotor. Your idea is very good, but I think it need a one way bearing somewhere, because if you use heli blades, their momentum will rip apart the gears when you cut throttle.
What if you put a 450 main gear with the clutch bearing in the middle and let this mesh with the four gears with the belt pulleys?
