That's not even the primary issue -- the shuttle is only for use by pax on airlines that pay to operate it, which AY is unlikely to do.
As others have mentioned, T3-T5, there is no way this can realistically be done. I'd book it, call, and plead for them to open up space on the 10:54 departure SEA-ORD.
