"The shutter stays open throughout. The four shots are taken using electronic shutter method with the sensor being shuffled about in-between each readout. As long as nothing in the image moves it will work. Presumably there will be some shutter speed limitations."
I put forward this suggestion:-
"If that is the case, I was just pondering that to move the sensor 1 pixel might take only a tiny fraction of the time of the set shutter speed. I was then thinking (hoping!), if that is the case, some guideline of shutter speed appropriate for lens focal length might permit even hand-held super-res. shots in suitable light?"
Any ideas here?
Cheers.

There will be finite time to achieve four exposures and as IBIS will not be available you will need to tripod mount the camera. For still life / product shots in doors or in a studio this is fine but if you're outside you will have to pray for a still day / evening or night otherwise it's recycle bin time.

Unfortunately with the Bayer array you can't have your cake and eat it for full RGB at each pixel site.
