The OP asked about standby instruments equipped (or not) with ILS indication. I flew one, shared it.
Someone says they had an FD setup, which is not the same on the instrument level. Since we're talking about standby attitude indicators and their add-ons, it seems relevant. You surely know the difference better than I could explain.
To get a standby instrument equipped with predictive steering commands would be a nice engineering trick, yet there must be a reason no one ever installed any such thing.
