A yoke-mounted GPS in either HSI or moving map mode is a good substitute for
a failed DG. Strictly for "situational awareness" of course! You have to
be careful in that the update of the GPS display is not instantaneous like
the DG's response to heading changes, so it's easy to find yourself "chasing
the needle". That's where the backup AI comes in.
