Multi zone A/C-heat is the norm here in TX, so nothing strange at all.
Your issue would seem to be the ducting that would be needed. It is so much harder to retrofit.
If you were to redo everything you might go 3 zone with 3 smaller units, better ducting flow and have a lower utility cost. But the conversion cost would be the barrier.
Split system not multi zone........ Never mind.
