You would probably have to count US1549, even though the cause was environmental there would have been a remote chance that an additional engine might have retained sufficient thrust to get the aircraft to a suitable (there's that word again) field. Against that, how many hull losses have resulted from a single catastrophic failure of or around an engine? UA232, LY1862,QF32 (almost) for a start. Having more engines that could save you also means having more engines that could kill you.
