As for the variant idea - my understanding is a variant is by definition a different version of the SAME image. So I don't think you can make images 2,3,4,5, etc. variants of image 1. Also many of the images which have the erroneous keyword also have one or more correct keywords. So I can't really copy/paste on a grand scale, because many of the images have (other) correct keywords that nonetheless don't apply to other images that have the erroneous keyword.
