It's about history repeating and main characters' lives ending up ridiculously similar to lives of powerful, famous, important figures that came before them. Got Paypal?
I honestly don't think their lives will turn out anything like Gold Roger, Mihawk, etc, it's just they have the same goals, so they're bound to take similar paths, at least at some point.
And Blackbeard… I suspect he's much more like a villain than Whitebeard is/was, Whitebeard seems pretty neutral... so I'm assuming he'll get his ass handed to him by Luffy and then drown somewhere out there in the middle of the sea.
