That would be fine, as long as you do your splits by body part- which could get complicated, depending on which Mesocycle you're in. You don't want to work the same muscle group two days in a row.
I would do 1 body part per day. For example, Monday was Back day, Tuesday was Chest, etc. I would also add a daily cardio on for 30-40 minutes.
I really loved doing Meso2 this way. My baby was pretty small and I couldn't manage to get a solid hour of time to myself. I would do cardio during the day and my weights in the night after I got the kids to bed. I'm doing something similar right now with GymStyles.
