I welded a QH to a SSQA plate. Was my plow mount. Made movng & working on impliments dam handy too.In my application, I installed a cheap Harbor freight 3PT QA to the loader bucket. Two bolts and a top linkage make a quick installation. I did it primarily for a blade but you can actually attach any 3PT implements.
I'll vote for scrapping the idea right now. Have you ever pushed snow on steel tracks? You wouldn't believe how fast a machine can move sideways on those fancy ice skates. I'd take a tractor with tire chains hands down unless you plan on corking the tracks to make them better able to grip the ice.
