Although obviously a little different mounting/pivot frame, it's basically the same a standard Cub blade. Not sure it's worth the trouble to import, but to each his own.
As far as permanently mounting, yes, I gues anything "can" be done. Unfortunately, there is only one lift mechanism on a cub, the center rockshaft, which also controls the lift for the snow blade, cultivators, plow, etc. You can affix the lift rod for the snow blade to the frame of the tractor somewhere by fabricating a mount, thus locking the blade in the up position. However, the hanger for the snow blade still uses the front tool bar mounting block, (under the engine/radiator) so you couldn't use the cultivators since they use the same mounting position.
You could mount and lift a rear field plow with that setup (snow plow locked in the up position) however, the snow plow mount hangs down pretty low under the engine and I'd bet that it would hit the ground once you got the front wheel down into a plow furrow, thus bottoming out the tractor, and would make it pretty difficult to plow a field. You can see this lower mounting point in the photo below from TM Tractors:
So, yes, anything can be done, no, probably not useful or practical at all.
