First: Pass your 0-5V signal through a summing amplifier (one input is
3.333V and the other your signal). The resulting signal should be
3.333-8.333V.

Second: Pass your 3.333-8.333V signal through am amplifier with a gain of
0.333, or 1/3. Your signal should be 3.333-5V.

Of course, this approach requires an operational amplifier (like the 741 or
358) rather than a comparator like the 324. This idea was not tested
experimentally so...
