Excellent observation! ... Exactly ... these signs are some of their triggers for breeding season and when they want to breed, food is the last thing on their mind. Also, instinctively the snake worries that it won't be able to get the warm constant temps it needs to digest, so they just stop eating for a while.

Unfortunately no. I've tried experiments in the past with extended lighting periods and precisely controlled ambient temps to try and get some imported animals to eat through the winter and it never works for me. Ball pythons are little natural weather machines and they know whats going on outside better than anyone no matter what the indoor environment is like.
