I love your ideas. I love anything that's different. Here's another idea: why not just put the car body of your choice on a Bronco or Ram 4x4 chassis. It doesn't have to be jacked way up. You can make it low yet retain the utlility of driving it in the snow. Or better yet, put airbags on it so you can lift it way up for the deep snow and lower it way down for cruising in the summer.
