I am going to experiment with what I"ll call a sugar frame - one of them is the size of two frames and the other 1 frame. I'll let the pictures talk. Assuming a live hive and the need for food, I will remove a frame (or 2) that is directly beside the cluster and put the "sugar frame" in its place. My theory is this will allow access without breaking the cluster and allow them to stay down in the hive instead of going up for a sugar board. In early cold spring weather, this may be an advantage.
Who knows! That's why it's an experiment.
