well the tail and wings look repairable... would it be possible for them to completely rebuild the center section from old pre-WWII plans?
also i have this book labeled
Final Cut- The Post war B-17 Flying Fortress and Survivors which has a pictorial history of B-17G 44-85734, and this was one of the 3 B-17 modified to accept a 5th motor for test work.
after the military sold it, the Bradly Air Museum receved the plane, were on October 3, 1979, a Grumman Albatross was flown through the B-17 during the storm, causing a huge gash in the center of the bomber.

had to be built by hand due to extensive airframe damageSo, in conclusion, they could very well rebuild the same pieces by hand.
