That's already possible: each mode can have a default-handler.  This
function is called in the case of an unhandled event.  If this function
returns nil the event will be forwarded to emacs.  Currently, there's no
such function for normal mode, but this should require only 
a few lines.  (btw, other modes like visual-mode could behave
similarily by just providing an appropriate default-handler)
