And I can confirm that at least one gate (70/71) has been used as a swing gate as recently as 2023. So perhaps there's some wiggle room in the airport infrastructure that allows gates to become swing-able when necessary. Still I don't think that you can simply swap out a commuter CRJ flight for a widebody international flight because they use completely different types of gates.
