crank-set (XT rear derailleur).
My thought is to add a 700c road-tire wheel-set with to this system and am
eager to learn if the SHIMANO HG-50 9SP CASSETTE can attach to a 700c wheel
applicable to this CAAD4 frame thus preserving the gear ration and chain
fittings.
700c (road; ISO 622) wheels won't fit your F700. It's a mountain bike,
and takes 26" (MTB; ISO 559) wheels.

If you were desperate to do so, you could probably get a 622 wheel on
the front by switching to a road fork. Normally this would be a major
handling disaster, since the road wheel is rather bigger than an MTB
wheel, but because your bike has a front suspension fork, an unsuspended
road fork and wheel would probably keep the geometry somewhat close to
the original. But it would be really stupid, potentially sketchy, and
functionally pointless. It might be the starting point for a pretty
amusing chopper, but expensive Al XC MTBs are not a good starting point
for that sort of thing.

use slick tires, which will make your bike much faster on the road
without compromising its geometry. If your taste for speed still isn't
satisfied, buy a road bike. But really, just get the slick tires.
On the off chance that what you want to do is use your gears on a road
wheel for some other bike, that's easily doable. Virtually every Shimano
8 or 9 speed hub is compatible with virtually every other Shimano 8 or 9
speed hub. The only reason some cassettes are designated "road" or
"mountain" is the suitability of the gears for a particular application.

I have a memory of the CDale Bad Boy coming with the aforementioned
wheelsets, but have found little evidence to that effect...
That is because it wouldn't work.
http://www.cannondale.com/bikes/02/ce/model-2mrbb.html
The Bad Boy was a rigid MTB frame equipped with MTB (26"; ISO 559)
wheels running Hutchinson Top Slick 26 x 1.0" tires. That's a very
narrow treadless tire, and looks exactly like a moderate-to-racy road
tire except for the smaller overall diameter. If the 1.0" really does
mean a nominal width of about 25.4 mm, that would equate to the fattest
tire most road racers would admit to using, or the skinniest tire most
road bike tourists or commuters would be happy using. Being contrarian
and improvisational, I have 20 mm tires on my commuter and 25 mm tires
on my race bike. I should really do something about that.
The Bad Boy rims are conventional 32-hole mountain bike rims. I don't
know the Mavic X139, and don't care to look it up, so I don't know if
that's a tough rim or a relatively lightweight rim.
You could run those Top Slick tires on your bike (on any reasonably
narrow rims) and they would do what you seem to want. With the goofy
Spinergy wheels, you'd have a pretty wild-looking urban bike.
I'll show you all once I build my 7-speed Factory Kuwahara BMX,
