could you not (I haven't tried this!) use a ratchet on the assembly so
that axle rotation one way turns the assembly, and the other way drives
the wheel?

Yeah, but I can't think of a good way to ratchet the assembly.

I've seen  ratchets made with a pivoting gear rack element in contact with a
24 Tooth gear.
Also, the small bungee racers had a ratchet mechanism also using several 16T
gears.
I'm quite curious to see what other variations of this platform emerge.

Yeah, I've made these sorts of ratchets before. The problem isn't so much making a ratchet as it is ratcheting the wheel assembly to the platform. If I had one of those free-spinning dark grey gears I could do it. I may finally have to break down (...) (25 years ago, 14-Jan-99, to lugnet.robotics)
