Would it be possible to make a hybrid 4K 3D movie?

I've been wondering if it would be possible to bump up the perceived quality of a 3D movie to near 4K levels by taking the left eye image (for movies where the left eye image is identical to the normal 2D stream) and replacing it with the 4K stream from the 4K blu-ray.

Either by using a full screen Top and Bottom 3D layout (for a 4K 3D TV) or by using a normal frame packed container but limiting to films that were released on 4K bluray with a 2K DI (but that still had a noticeable improvement in detail level over the 3D or standard blu).

My assumption is that the brain would blend the image together seamlessly with the less detailed right eye image, and the result would be the same 3D image but with slightly more detail.

Has anyone ever attempted this? Is it even possible? My assumption is based on the understanding that right eye images are already lesser in quality to the left eye image, but the brain resolves the images together in desirable quality regardless.
