Have you considered drafting some YC alumni into helping you do interviews? I'm imagining a system where applicants would have several interviews with YC alumni and then you'd interview the groups which get the most "yes" votes from your alumni screeners -- I'm guessing that after going through the YC program people get reasonably good at identifying what it takes to be a successful YC participant.
Of course, this would depend on the availability of YC alumni. I know I'd sign up to do it -- if I were a YC alumnus, that is -- but the fact that I spend several hours per week acting as an alumni representative on my alma mater's university senate (and committees thereof) marks me as being unusually prone to volunteer for such things.
