RVDT,
This is getting to be a fun thread. Let me weigh in a bit:
The theory that a wind against a slope would produce such a smooth flow that it would look like a steady descent is just that - theory. In reality, the typical turbulence and flow disturbance that the ground imparts on the air would make your case nothing more than a bumpy ride.
The flow that makes VRS is steady and smooth, with exact angles of descent (vertical will not do it, about 8 knots forward as you descend is the critical condition).
One can theorize a glass-smooth slope, and the perfect storm of slope, wind speed and flight condition, but in actuality, it is simply not possible.
