I like it too... what I run into is that there's an implicit 
assumption that module of name Foo.Bar.Baz *must* be found 
in a file Foo/Bar/Baz.[l]hs .  "module Main" seems to be the 
only one exempted from it.  GHC uses this all the time when 
going looking for a module's source code.  (it does help 
make sure that for any module name in a package, there's 
only one version of the source-code for that module...)  So 
I think we need to accomplish working out the kinks we may 
get in trying to break this assumption.
