No.

If you are to use FMGC data for the vertical part of an approach, you check and do a few things first and the doughnut becomes a brick.

The descent from circling minimums is a visual manoeuvre done with the landing threshold in sight.

The SEC flight plan is activated so you can put the wind in the performance page for the landing runway - in order to get GS MINI working in the right direction.

The doughnut is for descent and intermediate approach monitoring - using it on an approach will only end in tears, even if some of the time it may well be about right.
