The US did some pretty amazing repairs in the aftermath of the Pearl Harbor attack as outlined in this book: "Resurrection: Salvaging the Battle Fleet at Pearl Harbor" (I read it a couple years ago)
In short, most of the ships sunk or badly damaged during the attack were repaired and returned to active duty before the end of the war (the most notable exceptions being the battleships Arizona and Oklahoma). It's hard to imagine the fire damage to theBonhomme Richard is more severe that what happened the West Virginia or Nevada on Dec. 7 1941.
Now, if it is cost (and/or time) effectiveis a completely different question - I'm sure there are some bean counter types already looking at that aspect. But I don't think there is any question it can be repaired and returned to service if so desired.
