For ETOPS, why not get the thing lit on the ground and leave it running? At least you'd have a man with a 'Manchester Screwdriver' on hand to fix it.
That works well if you're entering ETOPS not long after take-off. I have a sector in western China where it's a few hours until ETOPS and policy is to leave APU on only if ETOPS EEP is within 1 hour of departure.
