I was just about to suggest gluing the thing on.  You beat me to it.

Subject: [Emc-users] Drilling holes in the back of a stepper motor

[EXTERNAL EMAIL] Be sure links are safe.

You have such a large flat surface area there. Design an encoder mount plate of 
similar size where the end result is also has a flat surface.

Rough and clean the back of the motor up, then use a decent polyurethane 
adhesive to bond it on. During the setup you could use a jig to keep it 
concentric with the shaft.
Design it in such a way that you can still replace the encoder if need be.
