Hmmm- as I recall- having worked at Everett during the first 767 flight, etc
767 had partial- minimum cable controls as the ultimate backup - and also used a RAT ( gimili glider )
KC-46 probably still has similar
KC-46 no doubt has EMP hardening along with a lot of 'normal commerical' wiring
KC-46 probably has upgraded-improved electrical alternate generators
KC-46 does not have thrust reversers- but for some special uses they might be relatively easy to 'add' reinstall
767 Structural fatigue improvements were designed in from ship one- extensive use of coldworking, and specialized one shot Electromagnetic riveting (Automatic Spa assembly tool ) since improved by nearby ElectroImpact Company ( long story about that going back to late 1960's )
767 generally has great ETOPS history.
IMHO slightly larger engines shouold not be a significant problem
( BTW there are minimal differences between 767 landing gear and B2 bomber gear, specifically including nose gear
)
