Is there any theological model believing in God the Son and The Holy Spirit to the exclusion of God the Father?

There are trinitarians who believe in God in three persons, and there are binitarians who believe in God the Father and the Son but do not believe in the personhood of the Holy Spirit. And there are unitarians who believe in God the Father but neither the Son nor the Holy Spirit. My question is are there any Binitarians that profess belief in a different two of the Trinity. in the interest of asking one question at a time I will post another question asking about God the Father and the Holy Spirit to the exclusion of the Son.
