at 10 mo i would say to gauge the routine on how happy your lo is, so assuming you are breaking up the eat and sleep somehow (as you described) and he is happy with what you are doing, then i say go for it. if he was younger i was going to say to work on nap extension in the morning but at 10 mo it is normal to have shorter morning nap...your routine is very similar to what my dd2 was doing. my only suggestion woudl be to watch out that catnap at this age as you might have issues with getting him to go to bed if he is not tired enough after a catnap.
