I also hope we can include something like this in Emacs one day.  But
I would not want to usurp the current binding of mouse-3, which is
handy in its own right.  We could instead trigger the pop-up menu by,
for example, depressing both mouse buttons (mouse-1 and mouse-3) at
the same time.  This feature is apparently already used on the Windows
build to fake a mouse-2 event using a mouse that does not have a third
button:

     The variable ‘w32-mouse-button-tolerance’ specifies the time
  interval, in milliseconds, for faking middle mouse button press on
  2-button mice.  If both mouse buttons are depressed within this time
  interval, Emacs generates a middle mouse button click event instead of a
  double click on one of the buttons.

But maybe it would not be ideal, especially since we don't yet have a
notation for pressing two keys at once.

Also, I would recommend to file a bug for your suggestion so that we
can better keep track of it.  Even if such a feature is not added
right away, the discussion can be useful many years later.
