Two Water Sources Operation for Sprinkler System

My Patio home is irrigated twice weekly by my HOA off of their water header. I have two zones and have located both valves. I want to tap into each zone downstream of the current control valve and add a new valve supplied from my water supply (with appropriate vacuum breaker) and control box. This will allow me to water at additional times. Is this possible or will the back pressure caused when I operate my valves damage the existing control valves and vise versa?
