How about this (as far as B777 goes):
The only relevance MLW has after an engine failure is that the Overweight Landing checklist will prohibit you from doing a F30 landing.
My opinion is that following an engine failure on a two engine aircraft one should land as soon as practical so long as landing performance is adequate. The last part of that statement is, of course, very subjective and it is desirable to use any time in hand to reduce weight.
Essentially what I am saying is that it is not necessary to spend an hour jettisoning 100 tonnes of fuel when a 4000m runway is available. Some intermediate ammount can be settled on, for example one which won't melt the brake fuses.
