i think your main problem would be with the root system itself. When you take a older mature plant and remove it from the ground. It may shock em to death. I know you never want to transplant or disturb a plants roots late into flowering. They should start to re-veg on 24 hours of light. If they survive being torn from mother earth to be planted inside. One or even a few seeds would of been a better option. Or maybe next season grow outside in a container you can move indoors or that you can transplant with little damage to roots
