Some of those other ones are complex and would need to be dyesub. I would prefer to have just the 1 key really. Though if going for a set, why not do the SSR colors? Same hammer and sickle legend, just different colors. So there would be a yellow on red, yellow on light blue, red on light blue, yellow on dark blue, yellow on green, yellow on white... and I think there is a few more combos, I would need to look it up.
