That sounds like a great idea ! As a kid, many years ago (back when dirt was new), my folks took me on a vacation that included YNP. As I recall, it was very cold, but don't remember snow being on the ground. I'll bet OF really looks great in snow on a sunny day - probably need sunglasses to reduce the brilliant white. If you do this, how about posting some pics when you can ? Would love to see them.
