Any more than they provide G/a patterns below DA on an ILS. Salzburg is a good example (LOWS) where the g/a for the special (200'DH) ILS is quite different to the higher 'normal' ILS due terrain.
Don't forget that in the process of manoeuvring onto the g/a for the 'other' runway if you wish to escape (visually, of course..............) you will be gaining height. Also worth remembering that there is nothing to stop you joining the visual circuit or another 'circle', but that if it is night, it is not a good idea to turn onto the g/a track OR downwind until you are at circling minima.
