My body quite likes biphasic rather than monophasic sleep patterns, and I spent around a year on this schedule. It worked well for me, but only because I wasn't forcing my body to do something it didn't want and I could fit it around my work. It can be hard to limit the length of your sleeping phases, and my tip here is to never go to sleep without something you need to do as soon as you wake up. In general it's far more healthy to hack your schedule to fit your body clock than the other way round. Outsource your admin work so you don't need to be awake at specific times, schedule any remaining meetings to happen during your most awake hours.
