Hi Super,
Well as you know given the motivation its possible to do pretty much anything with a 3D printer and a CAD program - that is if someone hasn't already done it
I'm not so sure we ever had the tracks with these clips though in the UK, Aurora was pretty late to the game in the UK, probably mid-70's till whenever Tomy brought them out (and the quality of the cars took a nose dive). The tracks we used to get in the UK had a clip/socket moulded onto the plastic track with wire inserts as I recall, but it's a few years back now and my old brain could be getting confused
