A variation on least additional votes:
Let f(A) be the fewest number of additional ballots (by friends of A) that can turn A into the CW.
Let g(A) be the fewest number of additional ballots (by opponents of A) that can turn A into the Condorcet Loser.
In other words g(A) is the same as the reverse ballot version of f(A).
When there is no CW, elect the candidate X with the largest value of the quantity g(X)/f(X).
