From what I remember of previous posts on this question, you are better off flying the thing all the way to the ground. Feathering, particularly at the wrong time or altitude could well turn what would be a stable approach into a messy descent well short of your preferred landing point.
Another consideration is that deliberately feathering will turn the blades onto an axis that will not bend so easily, perhaps digging in one or both sides and turning your asphalt bobsled ride into an undignified flip.
Finally, as far as I am concerned, once the gear failure was confirmed to be more than just a blown down and locked indicator light, the aircraft belongs to the insurance company so don't get too excited about trying to limit engine damage. Flying the emergency to minimise the risk of injury to yourself and pax far outweighs trying to save on some repair bills.
