You shouldn't have any problem unless one of the modules requires one of the others at compile-time. e.g. If one of the module imports from one of the others in the cycle, you might have problems.

But to use the module A's execute method, I will have to "use" it in module C

Not true. Class A must have already been loaded if an object of class A was previously created.
