Dave,
I agree that the starter will not put enough torque to hurt the design. However I think the ring gear is heat shrank on, in most designs. I think the interferance fit is all that keeps it from slipping. The thin ring of aluminum may loosen in all areas other than the spokes. When considering aluminum creeps over time, it may not loosen for a few years.
If in deed you are using a shrink fit, I would suggest drilling a few holes centered at the interface between the ring gear and flywheel and then pressing in pins.
If you already addressed this issue in another way, I appologize for the interruption.
My hat is off to you on the inovative approach!
