Reconfigure Arduino WiFi Shield to make it Compatible with Rover Robot

Lynxmotion Rovers, Sumo, and Tracked

Hi,
I had bought a Rover Robot along with an arduino WiFi Shield.

Now my problem is that since the PCB V2.0 of the rover robot is hooked to pins 5, 6, 7, 8 for permanent and since the arduino wifi shield uses the same pin 7 for handshake between them, the is an overlapping situation and the shield doesnt work.

The RobotShop technical team had suggested to reconfigure the wifi pin.

Will it be okay if the free pin 2 on the PCB V2.0 is connected to the bend pin 7 of the WiFi shield.
I need a way out of this problem ASAP, buying a new compatible shield is not ideal for me.

There are two possible solutions depending if you are more comfortable with hardware or software.

Hardware:
You could lift the contact on the 74HC00 and connect it to another pin. This would require some knowledge on surface mount rework.

Software:
You will need to update the WiFi library to use another pin instead. Pins 7 does not seem to have anything special about it so you could replace if with any other unused pin (pin 2 seems like a good option). This should be straight forward to do but might need some debugging and an understanding of C++.
