That may be possible! But the problem is if ever that happens, the memories he would regain are the ones before the brain scan, so he still wouldn't remember it all exactly. As an example, if his latest brain scan was the day he first entered high school, and attempted to use it with that method, the memories that he would retain are the events before the brain scan (which would not probably include events in index arc before he lost his memories, etc)
