two things

it would only help if the device is smart enough to not allocate a new block on the flash (requiring a erase of a block eventually) if the data changes are only 1->0

inverting all the data will thrash your cpu cache, and most things don't benefit from the change, so I think it would be smarter to modify the filesystem
