Well there was a window of opportunity for this to have happened, however that was circa 1995 and was predicated on being a (relatively short) transition period after which IPv4 would be turned off, something that was possible when the main Internet infrastructure was owned and operated by academic institutions and not commercial interests.

Also that the only real difference was the length of addresses, with the leading 4 bytes effectively being padding and thus could be simply discarded or padded as necessary.
