I have been trying to implement something similar, but LO is very hard to settle for the afternoon nap. I tried in vain today.
Her day was as follows:
Wake up - 8:30
Breakfast, play, etc.
Bottle and nap - 11:30-1:30
Lunch, etc.
attempt to nap at 4:45 with no success
Dinner, etc.
Bath, bottle, bedtime at 7:30
Could it be that she is sleeping in too long in the morning? I love it in weekends, but maybe I am setting myself up for a bad day?
