I suppose you could go the "Home Depot" route and thread it yourself if that's the knob you REALLY want on there. You'll just need to know what KIND of thread is on the new knob so you'll buy the right tool. I don't know what the tool itself is called though. I remember doing something similar with a door knob I wanted on a closet door a long time ago. I can't see any reason why it wouldn't work in this case.
