This is a good idea that I've thought about. Something not steel. They overdose the salt here in Iowa (the rust on year-2004 vehicles prove it). So something not as corrosive as steel would be ideal. I think full suspension is best for my area because of snow bumps and frozen sludge ruts at times (and hidden frozen objects under snow on roads) -- So I'm thinking of turning my '97 Super V into a winter beater with 26 x 2.2+ studded tires. Just have to find some full fenders that fit the weird frame. It's kind of sentimental to me though so not really sure if I'll beat on that bike (even moreso haha) during messy Winters and early Springs. Sure would be ideal for me though.
