I've done the same as Rand with a pair of T-32's and a BG-2 without bounce,
but with the 21mm WA diffuser on the one in the hot shoe. Works just
fine. I hooked a short TTL Auto cable between the two T-32's using the
sockets on the sides of the T-32's. This was easier than using a TTL Auto
cable between the BG-2 (or T-32) and OM-4 TTL socket . . . as I also use a
Winder 2 and have the BG-2 on the right, not the left. I used this setup
to assist a wedding photographer last October and would have used it again
for a wedding in November that I shot by myself if I hadn't bought a flash
bracket.
Since this arrangement has light coming from two separate sources I
recommend experimenting with which one is bounced and/or otherwise
diffused, with the camera body both horizontal and vertical. If you use a
T-20/T-32 like this, experiment with which one is in which shoe also. This
will show you what to expect and you can pick the lighting result you like
best.
Just one caution: With two flashes under TTL Auto control, especially a
pair of T-32's, watch that you don't get too close to the subject for the
aperture you are using. There is a minimum flash duration (and therefore a
minimum distance). Two T-32's together, without bounce or diffusion, have
a GN 1.414 times higher that a single one; it's about the same as a
T-45. A T-32 with the 21mm WA diffuser is about the same as a T-20 without
one.
Once you've got the TTL control to a T-32 through its hot shoe, you can
slave another from the connector on the side. Alternatively if you can get
it to the connector on the side of the T-32, you can slave another through
the hot shoe if you have it in a T-20 TTL Auto Connector (which has a TTL
connector on the back). The connections are all wired together in parallel.

I use almost that same setup frequently on my OM-2,2s, and 4T. The on
shoe tilted up at the ceiling at a point jus short of half the distance
between camera and subject. The other on my BG2 tilted up only about 5
degrees and aimed at the subject.

Mike,
I'm interested to know, battery consumption aside, whether what you
suggest will work - one flash on the hot shoe and another connect via the
TTL auto cord. I have an OM-4 and I am interested to try something similar.
