I'm afraid that won't work. I'm pretty sure the super resolution algorithm uses an equal number of frames on both sides, so reversing the order will give the same result. Replacing the frames will result in replica frames, leading to the compression artifacts being interpreted as real structure and showing up in the upscale as upscaled pixels. I noticed this effect when I erroneously left in the duplicate frames after detelecining the NTSC Star Wars.
