In addition to the above, when you try to do something like 1captain said, it tends to get the dish out away from the rotation axis meaning that there is more torque on the motor. The motors designed for small offset dishes have a bend in the shaft which is primarily there to allow the dish mount to go to negative elevations, however it also serves the purpose of keeping the center of gravity of the dish closer to the rotation axis, minimizing the torque on the motor. Anyway, I think that even if you manage to fabricate a suitable connection, you may just find that the dish is too heavy for the motor because it's center of gravity is out too far.
