Quick opinion check (It's 3D robot time again)

Oh yes, the changes would work just fine on both sizes, what I'm saying is that once I decide on a transformation and start fitting it together the parts will be different at different sizes in numerous ways. Mostly around the wing parts that aren't changing, but you can see it even in that simple rendition where the gun added at the scaled-down size interpenetrates the head/cockpit block when scaled back up because of the way that works out where two separate ends of the armature come back together.

edit: Oh, brainwave! I know what I'm calling this now - Coatl, after the development program got "rainbow viper" as a random two-letter designation, and the team testing the prototype painted the ring with bright bands of colour.

I'd involve this guy specifically if I could, because it sounds like a great totem animal for a war machine:

- Jumping Viper (Bothrops nummifer)

Jumping Vipers can be found in southern Mexico and in Central America: Guatemala, Honduras, Costa Rica, El Salvador and Panama. Locally they are known as "timbo" and "mano-de-piedra" (stone fist). They inhabit rain forests, but also plantations, wooded hillsides and rocky elevated places.

This chiefly nocturnal snake comes out in the early evening hours to feed on lizards, rodents, and frogs. It likes to hide under fallen logs and piles of leaves which makes it difficult to see.

As its name implies, the Jumping Viper can strike with force as this short powerful snake actually leaves the ground and may even stir up a cloud of dust. Its venom is haemotoxic. People have died from the bites inflicted by large Jumping Vipers.
