Probably. But you're reinventing the mecanum wheel, to some extent.

Take a look at http://www.andymark.biz/mecanumwheels.html and see if those are pretty close to what you mean.

Didn't say they wouldn't be. A screw like that would be like locking all the rollers on a mecanum wheel. (And then reducing the friction on said mecanum wheel, hopefully.)

It seems like one of the key elements is that its digging into the snow, so I doubt it would be very FIRSTable.
