Gibbard-Satterthwaite and Arrow say there's no such thing as a perfect
election method. It doesn't say that this implies that every method is
equally bad. All it means is that you have to decide what's important
and then choose the election method on that basis since you can't have
it all. Somewhat like politics in general, perhaps?

You could always do it by a combination of referendum and deliberation;
or in general, by a method that would be impractical to use on every
election (like repeated balloting).
One example of this would be BC's Citizens' Assembly for Electoral
Reform recommending STV as the new voting method; another would be New
Zealand's two stage referendum, where the first vote was about whether
the system should be changed, and the second was about what it should be
It's also possible that (in the right circumstances), you could get a
convergence to better methods. E.g. suppose election method X was
replaced with method Y which, though somewhat better, is not ideal. Then
later, Y is replaced by Z which in turn improves on Y. However, I think
that's less likely since voting reform is such a tough thing to
accomplish even once.
