I think it's important to point out that Mayuri didn't say Ichigo's Bankai can never be recovered; rather, he said that it will never be the same as it was. Ikkaku's was "somehow" restored by Akon (which brings up the question of why Akon knows how to restore Bankai but his Captain doesn't) but it isn't as powerful now as it used to be. I suspect Ichigo's Bankai won't remain broken, but it will doubtlessly become less powerful and he might have to augment it with some intense training.
