I think if the exhibit will let you do that, it is probably a good idea. But, they don't live long in exhibits.
We had a heavy frost last night here in VA. In another week, we will have another one. It will not make it to Mexico, with snow coming soon in your area. By the end of November, we will probably have snow, too.
It takes 6-8 weeks for them to make it to Mexico and that is with good weather, not snow storms.
They can withstand temps down to 25 degrees, but not for a long period of time.
