If I was you I think I would have a talk with my sim instructors and tell them that I would like to try one or two of these tight circuits with ongoing engine fire at or after V1 next time in the sim.
I have done it in the sim and it works. Not much time to think but thats not what you want to do.
Memory items complete and fire still burning initiate the turn needed (as you have briefed in your t/o emer brief)
As parabellum said leave the flap config - this giving a tight circuit and fast landing config
