Killing time again, and happened to stumble across this while perusing the series of tubes that make up the internet. Probably wouldn't have bothered mentioning it, but Piou mentioned he always wanted to see an Amy Rose / Sonic the Hedgehog bust. This is probably about as close as it'll ever get, since I doubt we'll see it in the official comics (sadly).
