Military EMP shielding issues are much more stringent than FAA requirements. Its MORE than FAA separation and FAA lightning protection requirements. As in a ' nearby ' ( say within 50 miles ) nuke EMP detonation pulse . The basic 767 has ( still ? ) minimum cable controls useable in the event of total loss of electrical power except for a RAT to power a few instruments. ( look up the GIMLI Glider ) tosee how that works ). .Now add FBW style controls for boom, special communication wiring, etc and the ' separation ' issue is the least of the problems.
And ' simply' moving certain wires futher apart is NOT simple- nor adequate to ' fix' - especially in a plane already stuffed and assmbled. re wiring your home AFTER completion would be relatively simple by compariso.
Extra grounding- alternate power paths, and special terminations are a small part of the corrections needed to comply to long standing MIL spec ..
