The hardest part in adding an ice maker to a refrigerator would be drilling holes for the wiring and water lines. You can easily drill into a refrigerant line and be sol in a hurry.
A friend of mine added an ice maker to a small chest freezer. On the third try he got it. The other freezers died during the attempt.
