Well, he can't "restructure", this isn't the NFL, but he could opt out of the last year, and then sign a new contract. Ultimately, though I think it all comes down to what the C's are willing to do for him. If they are willing to give him a 4 year, $60 million deal, if he doesn't pick up his $22 million option, then I am sure he will do it. However, if they are only willing to give him 3 years, $35 million, I don't see him agreeing to it.
