I suppose the thought that twin systems just doubles the
chance of failures has been noted? In the power world there
seems to be no obvious safety advantages in having two
engines. What do they say: "In a twin the remaining working
engine gate you safely to the accident site"....

Much of the problem with multi-engine safety is due to minimum control airspeed with one engine. This is less of an issue with in-line configurations, such as the Cessna Skymaster. One benefit of electric propulsion is that it's very compact and provides more mounting options. You'd never squeeze two rotax engines into an in-line configuration, but this would be very easy to do with electric.
