The problem I see is that the best Condorcet rankings-only methods seem
to have already been invented. So unless your method is going to be sub-par,
you have to agree with one of them for the first position.

If you don't like the inconsistency of mixing methods, you could go with
my other suggestion, to score based on the number of bullet votes needed
to make a given candidate into the beatpath(wv) winner. This is just
potentially a lot harder to calculate.

Using this rule, the winner could be assigned a negative score, if you
wanted, since it's likely that the winner could sacrifice some bullet
votes (assuming some actually exist) and still win.
