As others here have already indicated, my guess is that their problem, more than the technical and financial aspects, will be political. And even if relationships between Russia and the West improve, I can't imagine EASA rushing to give it approval when it will potentially steal orders from Airbus, not that I'm suggesting anyone there would have a vested interest at all!!!!
