You may want to temporarily wrap your eggs in a couple of towels and place on a heating pad on low, turning them everyonce in awhile and rotating them away from the pad. If you get them back to your body temp, they should start developing again.
One way I have found for bringing the temp of a styro bator quickly is get a several rubbermaid/tupperware containers with lids and fill them with very hot water. Place them in your bator, don't fiddle with the controls and leave them for a couple of hours, check the temp. Once you get your bator back up to temp, pull a container out and replace with eggs. When it comes back up to temp, remove another container and fill the spot with eggs. I would keep doing this until all of your eggs are back in and to temp, then if you have a turner, that is when I would quickly put it back in.
Or if your bator isn't full, place a hot water bottle in your bator full of hot water, the radiant heat should help warm your eggs up quicker. I bet some of them pull through.
Several years ago, so experiments were done with shipping developing eggs.
They would incubate the eggs for at least five days, then box them up and mail them to another person who would place them into their warmed up bator and finish incubating. They were successful at hatching healthy chicks, so I am sure you can get some of your to hatch as well.
