Well no rule prevents LHR-ZRH-LHR in J, YYJ-YVR in the far future in Y all on 014. Would need to go through a TA (or OTA might actually work since 014 would be cheaper and therefore the default here, but still needs to be checked as LX is otherwise the default).
That said, if the SQD split isn't as expected I wouldn't want to be the one chasing it down with AC.
Not a small sum and there are much better ways of handling it either via an unlimited flight pass or preferably just much earlier in the year before getting the SQM/SQD mismatch.
