Is it Islamically permissible for a newlywed man to stay with his wife and pray together for three days after consummating the marriage, absenting himself from congregational prayers at the mosque?

One is not permitted to miss congregational prayers except for a legitimate Shar'i excuse, such as illness or fear. A man's intimacy with his wife is not a permissible excuse for missing congregational prayers, according to the more sound opinions of the people of knowledge.
