Night worker with newborns?

Reading this book: Healthy Sleep Habits, Happy Twins

And it says they'll go to bed at 7 pm and wake up at 7am with naps during the day. I work 5pm to 8am and sleep 830 to 5. Obviously I'll need help the days I work but I can't even guess how I'll make this work with help. Can I put them to sleep at midnight and they'll wake up at noon?
