If you are going to stack them I would put assembly glue between them. Loctite makes some good products. A shroud is always best but maybe spacers are good enough. get a cheep lawn mower blade balancer and check the balance of the blade. Do a little grinding if needed. Being that far out is a lot of leverage so I would upgrade the fasteners.
