It appears to me to be almost certain that the queen that was in the hive has already left, with a large swarm. A further cast swarm may have also left, but let's assume not.
The honey super, at the moment, appears to be a distraction. Your hive isn't going to be filling a super with honey during this process, as a lot of the foraging bees have just left. So I would probably just take it off at this point to be honest.
I don't know what spare equipment you have. If it was me, I would probably split this hive into two as an insurance policy, with half the brood frames in each one (I would use nuc boxes, but you can use hives) leaving one undamaged capped queen cell in each one (pick the largest, knobbliest one for each). I would put the two new boxes next to each other, on the same location as the existing box, facing the same way, so that flying bees have a pretty equal chance of choosing either hive when they return to the location they know. That will divide the population fairly evenly between the 2 hives. Then leave them completely alone for a month to allow the queens to emerge and get mated.
If both do so, you have two hives. If only one does, you can merge them back together. If neither does, that's bad luck.
I wouldn't hang around in doing this - I don't know when those QCs are due to emerge but it can't be long.
