Wow, that’s a very clever idea. By splitting the zones into two sets, one set of which drives relays that supply ‘com’ wire to the other set of valves, you can drive a large number of zones. Thanks for sharing! It also sounds like an interesting math problem to find out how to split the zones to achieve the maximum number of valves.
