Essentially remanufacturing the wiring post install in the confines of a fuselage is asking for nearly innumerable defects.
Running a wire all by itself alongside an existing bundle is a bad idea as it will easily move and chafe and fatigue or wear through, allowing short circuits or corrosion.
Thanks for the insight Mech.
