Well the recomposited shots utilized the higher generation camera negative rather than the standard negative right? My understanding is that non-fx shots always used the camera negative while fx shots were copied multiple times to achieve their optical compositing. So when making the SE, those fx shots were cut out of the negative and their higher generation film elements were instead scanned so that they could composite digitally and avoid generational detail loss. So in this idea, those upgraded shots would still be replaced by the theatrical versions of those shots by scanning those spliced-out bits in storage and cutting them back in. Like I said though, this would only work if the Reliance restoration exists without grain removal and sharpening.
