This is a superb idea.  Diverse methods could be
alloyed, perhaps by simply voting amongst the
differing methods.  After all, you don't have to
vote more than once -- the "voting methods" are
really "vote counting methods".

For example, use ranked ballots.  Count them
using three different methods, chosen so that
their strategies conflict, and any strategy that
works for one method would be counterproductive
for the others.  Then take the social rankings
produced by counting the votes using those three
different methods, and use those a ballots in a
Borda count.


Results of counting the ballots:  (candidates
under each shown in rank order)

 Using      Using      Using
Method 1   Method 2   Method 3
--------   --------   --------
   A          B          A
   B          A          R
   R          R          B

Treat these outcomes as Borda ballots:

   A  5
   B  3
   R  1

At first blush, it looks like Borda could be
used as the metamethod because nobody would be in
a position to use strategy to manipulate it.
