You might after you take a look at this! The fine folks over at Make have been busy testing out the idea of shaving your rug. personal hygiene jokes aside, their results are pretty darn spectacular! It's appears to be a great way to get the look you want, the design you want, at a price you can afford.
For a little bit more crazy, try using fabric/carpet spray paint on the newly recessed areas before you remove the tape and you'll have a custom look for far less than major rug designers. So start canvassing sales online or on Craigslist for the perfect rug to scalp, there's a diy project just begging to be done!
