Yes. We will not change GNOME significantly in Fedora - those changes need to happen upstream.

The design team did someĀ  experiments with menubar replacements[0] - the one labeled "mega menu" looks closest to your suggestion. You might want to consider adding a comment there, linking to your suggestion.

I'm not quite sure what this means, but applications have to be modified to use remote menus, and the required functionality is only available with GTK+-3. So apps that have not been ported or use GTK+-2 (GIMP), Qt or a custom toolkit (LibreOffice, Firefox) will not just work.
(It works for Unity because Ubuntu applies large downstream patchsets to those packages which rip out windows' menubars behind the application's back; that is not an option for most upstreams or Fedora)

Just a couple of quick thoughts from my part, now let's move this to some GNOME list :-)

Cheers,
