How about doing that in software? You could take a pre-exposure starting at ISO 100.000 and decrease until you can calculate the where at which exposure you will run into clipping. That doesn‘t give you unlimited dynamic range but would avoid bad exposures.

What you're asking for is something that many of us have asked for for more than a decade, it's basically automatic ETTR. There's no reason to do any more pre-exposure than is currently done to generate the EFV image; the data just needs to be processed differently by the camera.
