But surely the prob hub will still compress until almost all the load is taken by the dowels or carbon -- effectively meaning that you're no longer spreading the load over a wide area but concentrating it on a small one.
I'd be concerned that this might then cause premature structural failure of the prop due to splitting, as the torque is now being transmitted through those dowels and not by the hub and washer themselves.
How hard can it be to simply re-torque the prop bolts at regular intervals anyway?
I have to agree with XJet here the hub thus treated will be transmitting the load on the "4" hard points. I would suggest that either the props are being over torqued or are not fit for purpose if they are crushing to this extent under engine munufacturers reccomended torque settings
