So technically you shouldn't have any problem, as long as you go-around at or before minima, if you do after, for whatever reason, it might be a serious problem.
It might be if you didnt check your go around climb gradient capability in case of engine fail before starting the approach.
If you started an approach with your actual gradient (one engine toga and flaps in GA position) below the required gradient you are not legal and Yes If you need to GA and then lose engine as you do so,you are in serious
I believe there is a 3.2% balked landing gradient (2engines/twin) that must be statisfied also.(speed VREF,gear down,both engines toga).
