I had the same question many years ago. A fellow with nearly 50 years of experince told me to split the brood boxs in half then put the honey super on the bottom box, then set the second brood box on top for about 7 days.
Also get rid of the queen excluder if you are useing one.
I second getting rid of the excluder. If you only have one brood box, I would add one the same size and move some of the full frames into it and replace with empties. If you have no, or little honey flow going on, then feed until they get it drawn out.
I personally used queen excluders to keep queen out of honey supers, as the bees won't abandon brood if you want to harvest the honey, but I would take several frames of sealed brood and move the frames into the honey super, and give the brood chamber the foundation to draw out, The bees will emerge and be where they need to be anyway as is the younger bees that aare the wax producers, plus the older combs will be natural attractant for more bees.. Would also consider feeding them, the nectar flow may well be rather slow this time a year. bees are not inclined to draw comb during a dearth of nectar.
