Not an expert, but at 3 years old she might be ready for no naps. Near 3, my son dropped his nap at home but at daycare/school the teachers continued to enforce naps. He did fall asleep easily for those naps, but then he would be awake until 10 PM every night, then sleeping through until 6:30/7 PM. If it were me, I'd try your "ideal" routine and maybe work towards no naps.
