Those are beautiful wheels. The frame they are on needs to be more ethereal, though. They are on a fairly pedestrian frame - but that might be just me and DH.

I wonder about the ride. Would it be like riding on cobbles all the time? (I'd sure like to find out.)

As to the other set of wheels, again the frame needs to better complement the wheels, and the ride would not be smooth as silk.

Both sets of wheels would be grand in parades, but that's about the only use I can see for them.
