However, if you want to be able to carry stuff on your carbon bike, buy a SADDLEBAG.

And since I assume you're not riding on a Brooks saddle, you'll need some bag loops. These are cheap, easily affordable for someone who owns a Civia Hyland and a carbon bike. LOL

This combination will be lightweight, versatile, easily removable, and will hold enough stuff for you. As for the "wind resistance" issue---are you serious? The weight of the rack and rack top bag will slow you down more than the supposed wind resistance of a saddlebag. The solution you offered seems a bit ungainly. Attaching the rack to the rear QR? Seems it would be a PITA if you have a rear flat. Seriously, look at some of Carradice's offerings. Their traditional saddlebags are great, but there's the SQR line which is narrower and mounts to the seatpost. It is a far better solution than the kludge you're looking at.
What about my problem? I have essentially one practical bike, a Cannondale Cross Disc. It does not have rack mounts, but I use the bike for everything from my daily commute to riding to my girlfriends apartment to the MS 150. I would love to own a pure road bike, but I am never going to race so I can't justify spending the cash, especially in this economy. I was going to buy a a bike more suited for commuting (Jamis Aurora was the top choice) but then I came across a great deal on a used Cannondale. Everything about it fit the bill except the lack of rack mounts. Saving a few hundred dollars is a big deal to me.
Would I love to own more bikes? Absolutely. Could I list specific bikes I want to buy right now? Yes. Do I need to save up for a down payment on a house rather than put thousands of dollars more into bikes. Yes to that as well.
