Like mikecva said, newspaper combines can be a bit stressful when the nights are really cold and there is two levels of brood with one queen... to avoid these issues, you can simply cage the queen that you want to keep, place here in the upper section of the brood and transfer both nucs (bees and brood all together in the center) into one ten frame hive body... with the queen in the center of course... give them two or three days to sort it out, then release the queen... keep in mind that you want the new ten frame to be placed where the strongest of the two nucs were... if your worried about fighting (not so much of an issue in this situation and this time if year), you can shake the weaker nuc's bees off of the frames in front of the new hive as you install them... older bees will go to the original location, then drift to other hives as they find that home is gone, and younger bees will go on in to the new hive and start meshing with the other bees... hope this helps.
