I think this is one of those subjects which could be debated over and over, but really only practical tests will ever provide real proof that a method does or doesn't work. Yes, it would take a considerable amount of time, but you also have to factor in the amount of knowledge you would gain by effectively building your own hardware to replace that of the USRP. Obviously, using old hardware would probably limit you to only a few channels at a time, but at the same time, if you wanted to watch the whole GSM spectrum, you'd need more than just a single USRP, and that's when it starts getting expensive!
Sometimes, these projects aren't just about the end goal, but also how much fun you have and what you learn along the way, you know?
