man xmodmap says

        keycode NUMBER = KEYSYMNAME ...
                The list of keysyms is assigned to the indicated keycode (which
                may be specified in decimal, hex or octal and can be determined
                by running the xev  program).   Up  to  eight  keysyms  may  be
                attached  to  a  key, however the last four are not used in any
                major X server implementation.  The first keysym is  used  when
                no  modifier  key  is pressed in conjunction with this key, the
                second with Shift, the third when the Mode_switch key  is  used
                with  this  key  and  the  fourth when both the Mode_switch and
                Shift keys are used.

...from which I recall some comment that indicates that while you can 
assign "any" key to be one of the extra modifiers, it's only the first 
four in this table that can be received as a completely-reassigned keysym.

Otherwise, you're relying on the application to interpret the modifiers 
(as xterm does, for example - in addition to the translations resource). 
That wouldn't be what OP was requesting.

clarification on this point was what I was suggesting...
