I would think 16/8 might hold some promise. Replicating the shortish days of spring.
I'm sure it's been tried before though. Maybe back in the mid-seventies when Carter was President and we had the energy crisis and we all put on a sweater to survive the bitterly cold winters by riding the razor's edge between death and life, between freezing and living, between waiting in line for 17 hours and getting a gallon of gasoline and running out of gas in the middle of the frozen tundra or maybe a desert and dying on the side of the road, just another victim of Highway rape and not the figurative kind of rape, but the real kind. I bet it was tested to death back then.
