The powertrain redundancy for the V22 Osprey would certainly be a lot simpler.
Not necessarily...
The cross-shaft between the props will still be necessary, since it is imperative that they both provide near-equal thrust. OTOH, you MIGHT be able to get an electric motor on the wingtip that is powerful enough, but smaller/lighter than the turbine. Putting those high-current electric wires to the end of the wings will be a problem itself...
Wouldn't two motors on each wingtip provide better redundancy than the cross shaft.
Low current wiring to the wing tips. Step down transformers...etc.
Where there's a will..
