Sounds like a sick idea, I've actually wanted to try this for awhile now, I think it would be hella interesting to see how they'd work out. My boss has a Rossi snowboard in our shop that he rides maybe once or twice a year...it's called the Undertaker, and it's a 195 swallowtail powder board, two of those would be ridiculous to try as skis. I've also thought about buying the longest wakeboard I could find and mounting snowboard bindings to it, cause wakeboards have a rocker style reverse camber, and are super fat... obviously it would be only for trying out in deep pow, but I think it'd be cool.
