Yes we can...
I wouldn't be surprised to hear that the designers at EC and Sikorsky and maybe elsewhere are rising to the challenge of creating a gearbox design that will deliver the kind of failure modes that do not result in catastrophic failure. Multiple load paths, controls protected (probably electrically actuated), and a guarantee of autorotation even if the whole lot goes pop. I'm sure it can be done it requires some motivation and 25 years after HARP I think it's time to do something that will deliver that paradigm shift needed to move helicopter airworthiness another rung up the ladder.
