I know Akainu is based off a Japanese actor, so certainly possible. Not sure who the other 2 are supposed to be.
Edit: Just read the link.
That idea about the guy in this recent chapter is really interesting. It actually sounds really likely, and fits with what we've seen. Since Doflamingo renounced his membership to the Shichibukai it would make sense for the Marines to come after him. Given his power level, an admiral would make sense. Its a little weird for him to be trying to do it sneakily and by himself, but that could just be his style. It explains why the bartender was shocked by the note telling him where to send the bill, as it was probably something like "Marineford" which would reveal who he was.
I like it.
