Occurs to me that if you can get your hands on some of the Devil Bat figures from the old Great Rail Wars games and add some clothing to them, you've got one side of a game set in/around the Tracking Site. Coming up with the servomek opposition should be easier than most things in the book, there are lots of androids out there. Might even be able to use sculpting dummies with some added putty.
Bob Naismith sculpted some very Kirby-inspired figs in Old Glory's Superfigs range. Probably find some useable stuff there, and all at the insane 40% off retail if you're an OG Army member.
Wonder if you could adapt some Traveller figs (15mm or 28mm) to use as well. Aslan and Vargr seem like they'd fit.
