Never thought of that angle, but that is certainly an interesting twist on the Boba we know and love!
Since there are millions of guys with his DNA, there could be many 'Bobas'. Even if one got killed every mission, he would appear to be successful when he 'reappeared'. Maybe Boba sends clones out and sits around his palace with the ladies.
That's why his armor and weapons change slightly. They're on a different guy.
