Not sure if this would be possible, but any chance a 35 mm print could be scanned at 1080, stabilized to match the blu, and the film grain only lifted frame by frame and applied to the blu?

Why scan a print at 1080 if one is not going to preserve it? With the money it costs to purchase and have it scanned it would make little sense to waste it in such a way.

Having two versions ..... one source from film and the other being and adjusted Bluray would make more sense for sure.
