Unless my eyes deceive me, he already is, at least peripherally. In one of the Tatooine scenes there's a shot of a ship under construction that looks an awful lot like Slave I. Timeline-wise, it makes sense. He's got a Fat Wad o' Cash after selling his DNA to some fella named Tyrannus, and decides it's the right time to spring for that fancy new custom ship that a bad-ass bounty hunter like himself deserves.
