The PureMVC Framework Code at the Speed of Thought

Right now, we are retrieving the proxy by having the facade instance of the other module within the module that requires the proxy.  Let's say for example, module A has a proxy called UserAccountProxy and module B needs to access the UserAccountProxy from module A. 

This is how we are doing it currently within module B:

var facadeA:ModuleAFacade = ModuleAFacade.getInstance ( ModuleAFacade.getKey() );
var userAccountProxy:UserAccountProxy = facadeA.retrieveProxy ( UserAccountProxy.NAME ) as UserAccountProxy;

Now my question, is there any other way to loosen the coupling between modules? A way that I don't need to import Module A's facade?

Thanks in advance.
