I thought of that as well, however the holes for screws or rivets would be sources for fatigue cracks.
There is decent area there on the fracture line, and unusually the fracture plane is parallel to the hanger, not perpendicular. An adhesive bond may work. So would a weld if the material is rated for weldability, such as 6061.
This is the point where a homegrown 3D printer would be awesome, the manufacturer emails you a file and you print it out. A high strength plastic such as delrin might work. However elastic stiffness ("Young's mudulus") is an issue, not just strength, for shift precision.
