Stray thought here..

Would a retainer system something like scaled up valve spring keepers on an
overhead valve engine work without becoming too massive?

Each blade gets a split "keeper" that nests in a bearing in the hub.  The
shank would need to fit through a seal into the hub far enough to get the
keepers on.  once the blades were seated the yolk assembly could be used to
maintain blade position.

Yes I think that might be a good idea.
