That's an interesting idea, I may try it. I get more use from a worn hub simply by taking care with bearing adjustment: just set it so it feels OK in the less worn parts and a bit loose in the worse parts, it will run with the occasional clunk but remain serviceable while you're sorting a new wheel (this is probably best avoided in the case of a traditional freewheel rear hub, as those axles tend to break). If you try to adjust out all the movement the bearing will soon fail, possibly catastrophically and miles from home.
