Mattyj-careful mate.
Just coz Air Nsn have cooked a couple of Dash8 motors this way doesnt necessarily make it possible on the saab. From distant memory you need rpm in the accessory gbox for ign on the saab. Maybe those more current than me will confirm or otherwise...
IMHO you should never knock a crew for thier actions unless you were in the cockpit at the time.
