Dave, Piggybacking the supply from one fuse to another is pretty common, especially in older boats. Just need to ensure the proper wire size to carry the load to all the users. Pre-made breaker panels have a solid buss bar which carries the power supply to each breaker. The piggyback wiring is philosophically analogous.
Personally, there are better ways to do it. If there's a place for a buss bar, you can route the power from the rotary switch to the bar then connect each fuse to a connection on the bar. I would not stack a bunch of separate wires on the switched connection on the rotary switch. On Touche', I have a Powerpost Plus, which is on the switched connection of the battery rotary switch. That is, when the battery switch is "ON", the Powerpost is live. A properly sized wire from the powerpost supplies a couple of buss bars in Touche's breaker panel. Each breaker is then supplied individually from the buss bar. Not sure about your comment on a fuse before a breaker. A better pic might help. You should have a fuse at the battery. I have these on Touche': https://www.bluesea.com/products/5191/MRBF_Terminal_Fuse_Block_-_30_to_300A Dennis C.
