If it has a separate draft gear box, the MT Z coupler should fit in the space fine, although it would need shims top and bottom, and should work fine for double heading. If the draft gear is cast into the pilot, I don't know how much work it would be. The biggest problem I can see is the length of the coupler. The 1016 shank extends much further than the 905, and there may not be room for the trip pin on the tender of the front engine.
