I wonder if you know how much money and fuel it costs to send any kind of objects into orbit around Earth. It's a few million US dollars in fuel alone, let alone the resources used to transport the goods, and construct the empty vessel. This whole system is impractical. Towing is an incorrect definition used here (To tow, the act of an entity with no power being pulled or pushed by an entity with power by guide of rope/cable/joint). Towing another shuttle would mean the first one pulling the second one into the air. The act of this, in addition to the tension gained on the cable likely connecting the two units would be far too strong, and would cause the first vessel to deviate from its flight route, becoming out of control. In addition to the actual force of the rocket engines needed to get the vessel off the ground, it would be far too much for the cable to handle, causing it to snap, and depending on where it goes, likely completely destroying the launch tower (spilling fuel everywhere, on the red hot launch pad after the recent blast off, causing a fire) and causing it to be needed to repaired before the next launch, or destroying the surrounding terrain, making it difficult to actually move the vessels to the launch pad.
It would not make any physical kind of sense to try to do this. Shuttles are massive, they can hold quite a bit of cargo, and they were used to move things into space to create the ISS.
