Every engine failure is not a catastrophy requiring to land on the same approach. When you are still doing ECAM the approach cannot be called stabilized. Approach starts at IAF. If you complete the actions by 1000ft (at least engine secured) you could go ahead and land. Otherwise discontinue the approach complete the procedure come back and land. Unless there is a good justification to do little bit of this and little bit of that together is not a good idea.
