Cause the regular reset is always available after all (and if that doesn't work, hold power button + tap the bottom screen corners). As for books+database it's just a matter of making a copy through USB, is that not simpler?
Or do you mean just pulling the system partition from the external card, not touching bootloader/recoveryfs? Cause if you include those, a brick is nearly guaranteed since the mod has no way of verifying that whatever is on the external card, will actually work at all.

One of the great features of the Kobo devices, is the use of a user replaceable "system drive"/internal uSD. This makes it almost impossible to "Brick" the device, because a scrambled OS can be replaced. There has been methods described that allow a clone image of the drive to be extracted without opening the case - but - no method to restore that image has been described, that did not involve opening the case. If you can copy a clone image of the whole internal uSD card to the external drive then use your process to replace the contents of the internal uSD with that in ram - except using the cloned image on the external drive. The external card would be able to hold the entire contents of the internal card. It should hold more that what you can fit in RAM. If you mod created the contents of the external uSD card, from the contents of the internal uSD card, why/how could it not know.
