I would like to go winter camping but would like to try it before I go out an buy a 4 season tent. I own a 3 season Marmot Limelight 2 and Limelight 3. Do you think if I brought the Limelight 2 w its rainfly and poles, and brought the rainfly for the Limelight 3 to go over the whole tent with probably a 6" barrier of air between the two rainflys, that that provide the warmth without the condensation Or is it just a bad idea?

Thanks for your time,
