I think that, now that the "Shen's last gift" DLC has been released, it would be really kick-ass if someone could modify the "Shodan voice pack mod" and the "Harbringer voice pack mod" to be used on the SPARK units. It would be something really cool to have a SPARK with a "Shodan AI" or "Harbringer AI" in your team. (If you don't mind that they are murderous AI's that will probably backstab you at the first opportunity)
