Crazy idea, but what if with the 12K sensor they took half the pixels and did one dynamic range ISO, and then on the other half did another dynamic range ISO for dual ISO. Say for example 400 with 14 stops, and 3200 with 13. The 400 has more emphasis on the highlights, and the 3200 the shadows. Combined together you get the dynamic range that intersects between the two subtracted from the total range, and thus the dynamic range becomes something like 18 stops. Essentially I'm guessing there's 8-9 stops of intersecting dynamic range for the two ISOs. The final result resolution would be 6K because it would still be half the pixels from each "capture."
For a VistaVision 16K the result would be 8K with 18 stops of dynamic range.
Now this is a very crazy thought. And, I don't know what it would do to motion. It might be possible for the motion to look fine. But I am talking about merging exposures of two pixels, so hopefully the resulting image doesn't have artifacts. But there is more than likely going to be trade-offs with this method.
