I wonder if you could cannibalize the wand and gate across the photodetector or build a loosely coupled LED strobe that would mimic the bar-code timing.

In fact, there was a semi-commercial product in Germany in the 1980s, which used a wand with the cable cut and interfaced to an external device to control the HP-41C. I don't have the name at hand (PBG or similar), but I believe, it is described in one of the CCD Club Magazines.
