I think you might have a hard time arguing that the most direct routing to PHX is via CUN. I'd be more straightforward: oneway to CUN (via any suitable routing) and asking CUN-YVR+YVR-LHR on AC for the return. Routing via YVR would not be outlandishly out of the way for a CUN-LHR routing, as long as you are on direct AC flights.
