IMHO that's bee feed, nothing more. Feeding cut-out honey to bees with supers on is just cheating to get around that. You don't give anything to a hive when there are supers on that you don't fully expect could end up in those supers. 60lbs isn't all that much. If you get a fall flow, harvest that deliciousness and then feed this to your bees to replace it, but make sure you're feeding it only into brood boxes. COULD some of it eventually end up in a super the following spring? Maybe a little, but do what you can and don't intentionally cheat.
