I do know this... the very first, and most important step would be getting Mr. Assange to do a photo verified STEEM introduction post, obviously under the name "reserved" for him, or any other username he so chooses. Either way, it needs to be legitimized. From there, I'm sure he's got enough dev contacts (or can get) for help to port the data over. It may not be able to be done in bulk per'se but, it should be easy enough to automate it chunks at a time.
