Yes the ladder business would be a definite put off. It could be run as low as one deep, plus two honey supers, plus the second deep on top. That would be less than what I have in the picture. I did get 4 medium supers filled and capped by that hive.
What I am proposing to do with a more or less permanent section of scaffold between two hives would give a much more forgiving scenario to work the hives. I dont think it is practical but would be a fun thing to do. If it gives good swarm control, provides re queening and gives good honey production that will all be a plus
