Wish you all of the luck in the world. But I'm sceptical. I killed my anceps outside. With our winters (canary islands) it needs to be bone dry in winter or it rots. And as you have already written, these plants can handle low tº as long as the day tº go up and sunny. Two weeks dull, humid, cold weather not above 10º is not a good thing. Winters in, summers out.
Keep fingers crossed, though.
