Nothing (not violating the laws of physics) is impossible in engineering if given enough time and money. As for the wood developing cracks over time all that matters is that it is designed correctly. All metal fatigues, also, some metals loose more than 50% of there strength over time, steel coasters are massively over designed to avoid fatigue problems. This is why things that can not be massively over designed such as airplanes and jet engines has hard life limit. For example a 737 might have a life limit of 100,000 takeoffs and landings, as soon as it did its 100,000th landing it would be removed from service as scrapped.
SOB had cracking problems because it was not designed correctly and the wood 'fatigued.'
EDIT: I am not saying it is a good idea, just possible.
