My problem with this approach is that it seems to assume an unrealistic degree of individuality. You're going to have to wait more than a day to see if you do or don't like some new version of yourself. But if you wait a week or a month, then rejecting this new version becomes pretty expensive. This version has been interacting with the rest of the world, which is not going to be keen about backtracking all their interactions with you.
Consider that you will have close friends and associates, and they will be evolving with you. If you and a friend evolved together in a way you both like, but then an old you disapproves while an old her doesn't, do you revert or not? What about your co-workers and clients and customers? How often will they tolerate your not recalling interations with them?
It seems to me that old version review has a place, but that one can't afford to invoke it very often, and that the cost of doing so increases with time, even though it probably takes some time to see what changes you like.
