I can think of several reasons it won't work. Off the top of my head:
1) There are just so many shitty links and LOLcats out there that the chances a shitty submission to YC is also on the frontpage of reddit is very small
2) The problem with reddit is that the signal/noise ratio is so high, not that there are no good submissions that make it to the frontpage. For instance this http://drnicwilliams.com/2008/02/22/zero-sign-on-with-client... is currently on the frontpage of both reddit and YC.
There are much better ways of doing it than this proposal. For instance use a bayesian filter to measure the submitted site up against previous submissions with high ratings.
