Nah, given that Boba is such a BAMF he'd have blasted his way out by now.
There are loads of novels that were written before Phantom Menace came out, that Fans pretty much took as an extension of the universe Lucas created. In one of them Boba Fett escapes and is rescued by another bounty hunter. He recovers and is still badass only with a gammy leg.
His background (in the novels) was much better, he was basically a dissaffected youngster turned bad. And im sure they hint at him being frustrated virgin too!
Obviously Lucas ignored all that fan stuff and rewrote Boba Fett into a doctor from Shortland Street. I preffered him before.
