I think that'd be a disservice to future applicants and YC.
Here's why: Any single application cannot represent everything YC is looking for. They invest in wildly varying startups. I was surprised when we were asked to come for an interview, and equally surprised when we were accepted...because YC had never funded anything in our area before (we're not web 2.0, we're not a hosted app, we're not social or user generated, and our design sense historically kinda sucks). But, history now indicates that YC is looking for more than merely more web 2.0 apps. They've now funded hardware, enterprise apps, sports related apps, and a lot more. There is no "YC style startup". Reddit was a great success, and one can find parallels in some of the other YC startups...but there are far more that don't fit that mold at all.
If you tweak to fit what you think is the YC mold, you may very well tweak out the really unique and interesting bit of your application.
