Motor Shield Revision

Hello world,

Would it be possible, in a future revision of the motor shield, to re-route the pin connections to make it capable of stacking onto the Wifi Shield?

i.e. :
DIRA - 4
DIRB - 7
BRAKEA - 9
BRAKEB - 8
PWMA - 3
PWMB - 10

If i were to prototype that, it should work, no?
