After the import is complete, yes.
import ModuleTest
ModuleTest.Data = Data

This works if the use of Data is inside a function that is not called 
during import, not if the use of Data is at toplevel or in a class 
statement outside a def.

Yes if ModuleTest imports Executable, but circular imports are a bad idea.
