Actually there were some heavy jet's approved in all cargo config. ICC Air Cargo operated 5 Airbus A-300 B4's and air Canada had the DC-8's in all cargo config. There was also another company owned by the owner of ICC who operated an all cargo DC-8 out of YMX. As well ICC had planned to operated a DC-10 freighter and had it on their O.C as well as their AMO, so thinks should go quickly for ACE. I hear they are starting this month.
