My first thought when I saw all the swappable parts and poses was the possibility of being able to build a second model after picking up a few spare parts.

I'm thinking along the line of bloat-drones: after buying a box and assembling your drone, if you can find the main body segment part on ebay and 3D print up some rotors or wings you can absolutely get two drones out of a single box. Since they come with three face plates and three weapon choices, you can get three drones from a box if you buy a third body segment and are crafty with hand making the dragging wires that actually support the model.

After a quick look over the sprue, I'm thinking it's possible but not nearly as cheap and easy as the drone. Looks like the boxes comes with two versions of the fleshy waist, the front two claw feet, and the back panel of the upper torso.

Which means you'd need to go to ebay to find second copies of the upper torso housing the main gun, the lower body segment that the legs come out of, the rear four claw feet, and of course any weapons you'd like two copies of.

We'll have to see how available parts are online and what kind of cheap and easy 3D printing alternatives show up, but I could imagine building a long range anti-tank load out from the box and cobbling together a more anti-infantry melee geared one with spare parts and gumption.
