I was thinking to use "Spray&Pray" as the Akimbo auto-shot name.
And I had a different idea when thinking about the snapshots. Normally people don't just shoot two bullets at once when dual-wielding, they increase fire rate by firing each gun in turn, but quicker. Could it be done so that when holding two single-handed weapons, shooting weapons in different hands, alternating, uses less TUs? Like, 50% less TUs to snapshot or auto-shot if your last action was a snapshot or auto-shot with a single weapon in the other hand? With an appropriate accuracy reduction, of course. So your first auto-shot, with a laser pistol in the right hand, would use 25% TUs, and if you auto-fire with the laser pistol in the left hand as your next action, it uses 12% TUs and has less accuracy. Then you auto-shoot with the right hand again, and every following one would use 12% - seven auto-shots all in all, as long as the hands are alternating. Snapshots, same thing - and no interface clutter.
Stunrods would need an actual double attack, however.
