Remember, you are not using 100% power for TOGA, and you have FADEC which will

Not using 100% power for takeoff? I don't fly jets but that sounds odd
to me. What T/O power setting are you suggesting is used in a 747? Is
it whatever the engine controller will allow when the power levers are
firewalled?

Also, the FADEC controller will not compensate in the way you think.
IIRC it adjusts fuel flow rate to maintain temps, EPRs & rpm parameters
to stay within limits. It's there to efficiently manage power and keep
a ham-fisted pilot from smoking the engine's hot section. I doubt it
will have any effect in a engine-out go around as it won't allow the
engine to exceed parameters.
