What exactly do you think is complicated? It’s essentially what you suggest in the first instance of feeding a board from another board but the original supply from a Henley and fused isolator? Plus seems sensible in my mind if I can to use RCDs in each board configured to prevent the previous outbuilding tripping?
The cascade of MCBs is all very well, but you probably will not get discrimination so if the last shed trips, all three MCBs will trip. At least the lights will stay on in shed 1.
RCDs don't help in the event of a short circuit.
