I dont think that an air ratchet would product enough torque to turn that bolt. It's the contstant pressure and pounding of the impact wrench that make it good for getting out stuck bolts.
Try sticking that screwdriver in there and see if that will hold the flywheel. Or see how much the dealer tools costs, maybe its not too much? And give a try at the pipe trick. I was amazed by how well it worked.
