Hey Glenn,
If you want direct flash illumination, it sounds like you pretty much have
the set-up that might come closest to providing a modeling light. If you
want to use diffuse light, you might try putting that flash in a light box,
and if available (I have not looked closely at that flash unit) use a remote
sensor or TTL to control exposure, and place a low-wattage lamp inside the
light box (like a night light), and outside the path of light from your
flash (to avoid a shadow from the flash). This will give you an
approximation on the _direction_ of light. It will help get the shadows to
fall where you want them. It will not give you any feel for light ratio
visually, nor will it give any indication (as I am sure you know) of how to
expose. And you'd be surprised the effect of modeling lights on final
images. Really good studio gear shut off the modeling lights for the
exposure either automatically or manually. I don't because I like the
effect I get. See:

Careful viewing will reveal incandescent light highlights on the chrome
wheels and pipes of the car (from the "focusing lights"). These give a
little color to the chrome. The exposure was with flash in light box,
calling for an f/22 auto-exposure (ASA 400 film) and since this was shot
with a Spotmatic II, 1/60-sec, Macro-Takumar 50mm f/4 . The incandescent
lights would not give a good exposure at these settings but the highlights
from them do come through.
