I was thinking you could remove most of the larger cogs and just have the smaller ones, and a small front ring (with a longer hi-lo screw on the derailleur to limit range), but I guess that would be stupid.
A friend of mine did similar for the national last year. For the vast majority of hill climbs I cant see anybody needing a full range 10 or 11 sprockets...
Cool.
