No amount of bleeding will fix it. Just have to put a few hundred miles on the car and get new seals broken in.
Just another thought.

If your calipers were rebuilt with new seals, this could be the culprit. A soft pedal is the symptom and for me, cleared up after a few 100 miles.
Air in the lines is another obvious, easy thing to chase. I usually bleed my brakes a few times with a few drives in between to get all the little bubbles out for good.
Neither of these will necessarily cause a "pedal to the floor" symptom though.
