If the queen is around in the original box, you should find eggs, and all should be well. If not, I might put one of your queen cells in there.
You didn't mention whether the queen cells where supercedure or swarm cells; or why you chose to re-queen. But:
I would be tempted to pull the queen cells in the second box before installing the new queen... and,
I would be tempted to try a third split in a nuc with the queen cells.
All that having been said, my besetting sin is to get greedy about making increases, and leave hives too weak.
