Is it possible, and is there an example, of how to modify keyframes on a clip using an CEP/JS extension?

CEP panels can use ExtendScript to do that, yes; here's how.

It appears that @justintaylor is correct that there is no way to adjust the keyframe interpolation correctly. 😞

I've resorted to doing my own interpolation and adding keyframes to each frame of the video.

You can't modify interpolation, but you should be able to add/remove/modify keyframes.
