Jeff, In my experience, you can do this, but when you invoke the method, it does not invoke within the memory space of the original component. It invokes the method as if it were a free-standing method. Therefore, it does not have access to THIS and VARIABLES scopes of the CFC.
This is what I have found when testing, but I may be wrong. -ben .......................

Becuase of that, you can treat the method as a key in the scope struct and create a reference copy to the "a" variable.
