There was a similar (in spirit) project to upscale and resample Avatar the Last Airbender [1] because the original DVD release was so awful. Shortly after, Nickolodeon released a blu-ray boxed set that was quite a bit better than the DVDs, but it still had some issues. Doesn't seem anyone has decided to upscale it again [2].
