I see absolutely no problem in going floorless that time of year, or any other time of year for that matter. Your combo tent idea sounds pretty bomber and I’ve done it that way many times. The only difference between what you’re thinking of using and what I have used in the past is, I usually bring an Arctic Oven and one or two floorless tipis, depending on how many people are going. I have on occasion just brought one of those bigger base camp shelters, when there were just two of us going, and I’ve also just used a 6 person Cabela’s Alaska Guide Dome on one occasion. If you’re going that late in the year with multiple people, it’s nice to have a big, fat, base camp with multiple shelters, because you will be spending more time there given the fact that your days are much shorter. I think having a designated sleeping tent, along with using a nice sized tipi for your cook shelter, and just hanging out in shelter, is almost the perfect base camp configuration. The latest I’ve ever gone down there is in late December, right before Christmas. There were four of us on that hunt and we brought a large Arctic Oven sleeping tent, a 12 person Seek Outside tipi w/wood stove for our cooking and hanging out in shelter, and a Titanium Goat 8 person tipi that we used as an outhouse. It was really nice to be able to go into a designated shelter, take off your wet jacket, and sit down on a camp toilet to do your business. That was probably the cushiest base camp that I have ever experienced and it was well worth it, given the fact that we spent so much time there with there being only about 7 hours of daylight/day.
Here’s a few pictures of some of our Kodiak base camps.
