As a person who finds panentheism attractive, I really like your description of god as emergent property but would not agree that is resembles pantheism. If pantheism is the belief that the divine is in all and is the totality of all, it doesn’t fit near as well as panentheism, the belief in which the divine is in all things as in pantheism, and gives unity to all things like in pantheism, but in addition it is greater than all things: making god an emergent property. Just a thought.
