It is possible to shoot handheld yes, of course depends on what you are shooting.
But I'm working on the double grip. And re designing the top. Will have servo motors to move the viewfinder and another one to open/close the lid. Also will have a shutter counter and an axelerometer with a digital display. The PCB boards are on the way, and more custom parts.
4x would be ok, but can't compare to 15x focus.
