When you view this again, see how much of the shaft taper is still visible forward of the prop hub. Maybe a chance for a shop to machine the hub to allow it to sit further forward, thereby making room for a proper double nut job.
If there is no extra taper to work with, then maybe machine off some hub on the aft end. I'm sure a prop shop would have good suggestions.
And, of course, make REAL sure the prop is not sitting on the key. I use prussian blue for the test.
