I'm just remembering another issue with this approach: you also need to take ECC into account. Flipping a data bit from '1' to '0' may require flipping an ECC bit back from '0' to '1'.
Thus, for such an approach to work, you'd also need to have control over the spare area, where ECC and bad block information is normally stored.
