AGAIN - NOT AN OPTION.
Maybe you should give the snake to someone who can take care of it properly. Or you can just let her starve to death. Or you can find a closet space with temps between 40-60F.
Putting her outside or in a cooler room would be the equivalent of putting her in the freezer, and I actually like my snake.
I don't think you like your snake that much. What you snake is doing is shutting down because of your husbandry. IT IS NOT THE SNAKES FAULT! It is your fault for not understanding or listening to advice. If she has been eating rats and suddenly shuts down there is a reason. You can figure that out on your own or ask real questions. Either way it is about the snake and not YOU!
