Sure, but if he was a pirate before getting built, it's hard to see why the Marines would make him stronger. Granted, he's a Shichibukai, but the Shichibukai are one of the three world powers -- the others being the Marines/World Government and the Yonkyou. In short, they're rival powers, even if they have a truce.

He knew Dragon was Luffy's father. Either Garp's been spilling the beans (plausible), or Dragon knew Kuma well enough to tell him about Luffy. Or I guess the Marines could have otherwise collected intelligence, but telling Kuma that would be kind of pointless.
