Rat's got a crooked snout- too late to fix it?

I somehow managed to fleece this guy's entire face without realizing his snout is... listing. Badly.

Is there any way to salvage it without tearing it apart? The mouth is already lined and sewn, and I can't fathom a practical way to get a "skeleton" or framework in there to correct it. If I could just...twist it somehow and have it stay put.

Any ideas you can throw at me would be greatly appreciated!
