In the project I am working on, I have a limited space with which I can work. I am using an Arduino Uno with 2 Adafruit motor shields, and when I stack them using normal, female stacking headers it is too tall to fit. I thought that one way to solve this would be to lay them out side to side rather than one on top of the other. So, instead of this

+--------Motor shield 2 ----------+
|||||||||||||||||||||||||||||||||||
+--------Motor shield 1 ----------+
|||||||||||||||||||||||||||||||||||
+---------Arduino Uno ------------+

it would look like this

               -----------------------------------------Wires -------------------------------           
+---------Arduino Uno ------------+    +--------Motor shield 1 ----------+    +--------Motor shield 2 ----------+

Would this be possible if I were to connect all of the pins with wires, and has anyone successfully done this before?

It is possible to have some success with this, but keep in mind that the longer the wire, the higher the inductance and voltage drop across the wire. Prefer to use a star topology rather than a chain topology, with the Arduino in the middle of all the shields in use.

    Also you probably only need a few wires connected. It looks like the motor shield uses 6 pins, 2 I2C pins, pins 9 and 10 (if using hobby servos), power and ground. – Craig May 21 '14 at 19:08

Yes, no problem running individual wires, and also like Craig says, only run the wires you need. For some inspiration, here's a project I did with a bit of hand wiring. And then there's this project with kinda epic wiring.
