What about the Long-EZ?
I would submit it already manages to "look" like a dynamically stable wing in pitch, so that the contribution from the canards may be mostly better trim and manoeuvrablity rather than primarily added decalage
I'd be surprised ... But who knows, might learn something!

Also, the only evidence the 172 article produces is a fairly dubious experiment where the author loads one at its rear c of g limit and finds it is still stable.
Far as I remember, what he did was to tie strings to the outer end of the stabiliser, and observe the direction of the vortices generated. From that one could readily observe the direction of the lift being generated. Have to admit I'm only 75% convinced though, would love to see it myself...

Negative on the aircraft designer question.... Anyone else?
