Joe, there was a roofer killed in Asheville five or six years ago when he came into contact with a service drop.
This was a commercial building and I don't recall the details so I can't remember the voltage, but in any case this warning would have saved him if he would have adhered to it.
Wa2ise, I would separate these conductors, and even though there may be some who would say the Armour may not clear a fault of 100 amps, (put a megger at 500 or 1000v between the points for a test) I would feel better about this than the possibility of the Armour carrying the neutral load.
Personally, I'd try to run an external EGC between the panels. (yea, yea, yea, I know
