Here's one...
2 flash on wireless triggers (in lightbox/softbox) - these fire at the same time to give 1 more stop of power for the same setting.
Hence, if both are at 1/4 power, they give 1/2 power of a single flash while retaining the charge at 1/4 usage. (ie. can fire roughly 4x w/o a long recycle time)
Since its indoors, set ambient to as dim as possible after setting up the shot (plus focusing, etc)
At f8, f11, I'd think its shutter speed should be slow enough to be in the seconds range.
Choose a shutter speed such that there is enough time to trigger the flash via remote (4x thru the PS sequence )

Whallah!
35mins after typing the above, I just had to show that its possible (and really doable )
2 YN560IV on light stands pointed to the same silver umbrella.
1 silver umbrella on the other side for fill
Flashes at 1/4 power
K1 set to pixel shift, M mode, ISO100, 5s per frame, f8 (lens : Vivitar 55mm macro)
2s timer release
Focus is on the Yashica Mat name plate.
Basically, I set up the shot, and focus, turned off the lights that would affect the ambient exposure.
Released the timed shutter released.
Once picture taking started, I started my stopwatch and manually triggered the flashes with a YN603N II within the interval of each 5s frame.
Full size uploaded on my flickr (just click on the sample and navigate there )
If a half baked strobist like me can pull this off after thinking of it within 35mins, I'm sure others can too.
