Do it on a Novatec double fixed hub, have done for years. At times i have run double SS freewheels.
Safety element is correct, a shop staffer would not be able to say do it or it can be done for liability issues. So i wouldn't slate mechanics for saying no.
The risk is less thread engagement over using the correct full thread for a SS freewheel.
It's well covered already on this thread.
many do it with no issue, you do it at your own risk and risk of damage to hub.
