The few that come to mind for me are:
If Hamed had hung around:
Hamed-Pacquiao
Hamed-Morales

And:
Trinidad-Mosley at 147 in 2000 (if Tito could have just hung at 147 for a little while longer)Oscar-Quartey II
Whitaker-Norris at ~150 catchweight or 154
Mayweather-Tszyu
This to me is the biggest fight never made. Or at least the one I would like to see most.

Wlad Klitchko vs Lewis also.
