If you're going to have an advanced runoff method, why not do something 
explicitly more Condorcetian? Perhaps something like:

Determine the Schwartz set. If it is singular, the candidate wins,
otherwise: the two highest ranked members of the Schwartz set, according 
to some Condorcet rule, advance to the runoff.

Another option would be to use D'Hondt without lists, based on a good 
Condorcet method, to elect the two candidates for the runoff. But that's 
too complex, I think.
