I have, we take backcountry ski/snowboard trips to huts in different areas. It is pretty freakin' cool, but you need to know it is not hiking at all. Winter travel is so much more difficult and dangerous than summer travel. A few miles on dirt trails is fun, a few miles in the backcountry in winter could kill you. Travel is slow and painful. Be prepared to suffer. Weather can move in and stop you in your tracks. Going off course can result in getting lost and needing rescue or dying. I'm not even going to get into the intricacies and skills needed to travel through avalanche terrain.

Are you planning on snowshoes or skis? Snowshoeing is slow and brutal in certain conditions. Do you have the proper gear? Radios? Beacons, shovels & probes? Functional underwear/outerwear? You can go from sweating your balls off to freezing in about 5 minutes. Do you have anyone more experienced to go with? There are classes (some free) that can give you some skills and knowledge. There are also clubs like CMC that have trips you could join. If you're serious, start planning now.

The 10th mountain huts fill up pretty fast, especially for the spring dates. If you are serious, book soon. There are a few huts that have a mellow approach, some are a death march in winter. Some have limited exposure and flatter approaches and these are more accessible and book faster than more remote ones.

Remember, once you leave any populated area; you are on your own. No one is coming to help you. You will need to self-rescue. This also means your wife could need to rescue you. I am not trying to discourage you, only prepare you. Shoot me a PM if I can help in any way.
