I did "no gyro" (no AI/DI) NDB approach on my initial JAA IR skill test and of course I did assymetric approach & go-around as well. It's not really that difficult and it's quite safe (we did zero thrust as opposed to feathered prop). Your examiner should explain what he expects from you during the pre-exam briefing, so there shouldn't be any surprises.
