Doubtful. (Actually I’m certain you’d have zero chance with WS.)

And I’m amazed that AC was even able to bend their rules, much less actually do it. You were very lucky.

I’d suggest you never, ever, ever book an itinerary like that on multiple tickets — on any fare other than full fare Y, J or F - on any airline. It’s a risky way to travel. Find a good travel agent who can construct the ticket that you need ...it’ll be infinitely safer.
