I finally settled on a grip/flash bracket for the SWC that suits my needs. I thought I'd share so others may have a starting point if they encounter a similar issue. I decided to use the Hasselblad Flash Gun Bracket Left Grip 45020 for several reasons. 1) it's light and compact, 2) it has a flash cold shoe, 3) is has a cable release built-in, and 4) it's relatively inexpensive. The problems were that the camera attachment point is designed for the older style Hasselblad camera plate, and the positioning of the SWC on the plate (even if it did fit) would make it impossible to remove the dark slide. The solution was rather simple. I had a small aluminum adapter made that fit into the grip's existing mount and that could accommodate (on the top) the Hasselblad Tripod Quick Coupling (45129) Release Plate. This way the SWC could be mounted and unmounted rather easily. The body now sits further back to accommodated the dark slide and slightly closer to the left hand grip. This makes for a compact SWC and grip, that allows a flash to be easily mounted, or a remote trigger in my case. This is what is all looks like. The extra bit on the cold shoe is because the trigger does not fit the Hasselblad shoe. There is still plenty of room for the neck strap as well. I hope this is helpful to some...
