I think this strategy could work out fine as a psychological lifeline. Sure, you probably won´t make as much profit this way, but if you hit a bad losing streak with max buy-ins the first time you move up, you might be scared to try it again. If the opposite happens, and you win a lot at first, you might get hubris and start playing bad with negative consequenses to your bankroll and skills.

Also, when adjusting to higher stakes you need to adjust yourself to the variance. If you lose double as much in one day than you have ever lost in one day before, this most probably will affect your mood which I think never is good.

As a conclusion, I think this strategy could work out good for many people when they feel like "teenagers": They are not quite children and feel the lower stakes tables are "childish", neither grown-ups ready to have house, wife and dog at the higher stakes tables. After all, the stakes always increase with a factor of 2 which is a pretty big leap.
