The real issue is not removing the bolt; it's re-tightening it to spec. Assuming you have a nice 24" breaker bar, you can simply have someone bump the starter to get it loose. To re-tighten it using the method you mentioned, you'd need to remove the crank sensor on the back side of the engine low where the bell housing meets the block, directly on top. A second method is to jam a screwdriver into the ring gear. A third is to buy the handy dandy crank pulley holder from IPD and last but not least, the rope trick whereby you pull a spark plug (your choice, feed a length of 1/4" rope down into the cylinder and let the piston come up and compress it until it won't move...crude but very effective.
