I am planning on doing that too for sure.

I have wondered about doing that. Seems a good idea. How does the prop hub "screw on against the magneto centre"? Do you use a centreing spigot and six axial countersunk machine screws? Placed 30 degrees different to the six prop retaining bolts?
I then make a collar to hold the magnet for the ignition that goes over that magneto center, and is held with a set screw for timing adjustment.
