I am no big iron guy but I have a lot of multi-engine time.
When one engine malfunctions, it is time to go to the nearest suitable airport. The theory that it will fly just as well on one is fine. It will get you to the airport unless, and a good friend of mine was killed this way, the same thing that caused that engine to quit could cause the other engine to quit.
Never assume that can’t happen.
My friend was highly experienced, jet fighters over North Korea and years of flying before and after. New hire on the flight line, improperly supervised, fueled his plane with jet fuel. Both quit over very rough terrain.
As for the expense and problems involved in repairing the aircraft on an airport far from home base, that is a management problem How to manage an emergency is the captain’s problem.

Wow. What type of aircraft was he flying?
