Silk road tentative trip - anyone in?

With a month and a half left until I start professional training, I have been getting a bit restless and am torn between taking one of the trips outlined below. I chose this route because it covers South and East Asia, goes through the Karakoram Highway and mountains which is part of the Silk Road, and enters China in Kashgar, which is where The Kite Runner was filmed and is en-route for "modernization" (read: demolition of Uyghur compounds). The part starting from Beijing is flexible. Anyone interested in joining?
