There is such a hook (not exactly a hook in fact, but quite similar).

See the function Gdk.Event.Event_Handler_Set (I am wondering if it was already
in the last public version or is only in the developpment version, anyway the
C function is gdk_event_handler_set).
With this, you can replace the default event_handler by your own function,
which should do the following:

   - Modify the queue as you said in your message
   - Process the event by calling Gtk.Main.Do_Event (E)

You might want to look at gtk-macro.adb (the code there is not finished, but
will give you an idea).
