This may work on something with the complexity of a microcontroller or SoC, but becomes tricky beyond that. Any peripherals, especially removable ones would still need to be rediscovered and reinitialized on boot. Network connections may have died/reset while the system was off. Essentially, this scheme has all the major complications of resuming from sleep/hibernation in practice.
