Some quick pictures to show progress. My idea here is that the Tau (being my main army) have figured out a way to interface with Necron Canoptek tech. It's not a full fleshed out idea, but it keeps me happy and let's me use little bits of Tau tech on my Necrons.
I left the "driver" off and replaced him with a Riptide shield. I like the idea that the Stalker is being controlled by a customized Tau Drone.
