"Couldn't you just use bidirectional TVS' (at, say... 10V for "X" and
8.2V for "Y") across ground and the inputs? So if an op-amp failed and
yanked the output the +/- rail the TVS would clamp it?"

yes, you could. I haven't looked at it in a while, wasn't there
another problem with it, like it wouldn't clip in the negative or
positive direction?
