Look at it this way, you are on final airport elevation near 5000, temp 25C, flaps 30 or 40...down to Vref around 140kts, so almost all of your energy is gone, and lose an engine. You now have to get the engine spooled up, all the bleed/icing etc off, balanced and to flaps 1 (the AFM basis for climb)...and not drop below the MDA...and is your climb near 2.5%
For a start, the AFM requires the aircraft to be able to climb at 2.1% in the Approach-climb config at the airfield elevation, so that is the immediate go-around taken care-of.
What terrain clearance parameters
are you going to use for the rest of the Missed Approach?
