Preferential voting probably won't work. I think the two-party system is a bit of a result of culture: we feel the need to shoehorn every political issue into an "us" vs. "them" debate. Don't forget, however, that there have been third parties in the past that have been popular enough to carry states. Unfortunately, they are generally one-trick ponies that are only present in a single election.
