I don't see a problem, but at some point, when you have reached the point that you've put together a reliable routine (towards the end of the program) that you do the full routine at the time of the OBE practice, whenever that is.
I usually do energy work during the day (it wakes me up more than relaxing me, but we're all different) and the routine early in the morning, not every day, but I've been doing this for a number of years now.
Split it any way it works for you, it's what we want, for you to succeed.
