If you can collect together a super cheap hub and derailleur I'd say give it a go, worst that'll happen is you break the derailleur and I guess use one of those conversion kits to turn the wheel into a proper fixed wheel. I'm sure some people in here will have useless derailleurs/shifters/cassettes that they can give you.
Make sure you take a video when you try to ride it though so we can see why exactly it fails
:(
well then, that's my christmas project crushed under the heel of reality.
