This is all quite possible. Also, even if an official release doesn’t happen, maybe some 35mm fan-preservations may come out, which will make Despecialized unnecessary.
I think your work is fantastic Harmy, and it certainly won’t be unnecessary. I really like the sharpness of the Blu Ray, and a 1080p version of Despecialized using some 35mm elements would be fantastic. Your work won’t be overshadowed or forgotten.
Well, from what I’ve seen, a really good IB Print restoration should be at least on par with the official BDs in terms of sharpness.
