1 Kings 2:19-25
19 So Bathsheba went to King Solomon to speak to him for Adonijah. And the king arose to meet her, bowed before her, and sat on his throne; then he had a throne set for the king's mother, and she sat on his right. 20 Then she said, "I am making one small request of you; do not refuse me." And the king said to her, "Ask, my mother, for I will not refuse you." 21 So she said, "Let Abishag the Shunammite be given to Adonijah your brother as a wife." 22 And King Solomon answered and said to his mother, "And why are you asking Abishag the Shunammite for Adonijah? Ask for him also the kingdom-- for he is my older brother-- even for him, for Abiathar the priest, and for Joab the son of Zeruiah!" 23 Then King Solomon swore by the LORD, saying, "May God do so to me and more also, if Adonijah has not spoken this word against his own life. 24 Now therefore, as the LORD lives, who has established me and set me on the throne of David my father, and who has made me a house as He promised, surely Adonijah will be put to death today." 25 So King Solomon sent Benaiah the son of Jehoiada; and he fell upon him so that he died. NAS
Just where do you see where Solomon refers to Bathesheba as the queen mother? In fact the request she made of Solomon resulted in the death of Solomon's older brother. Honoring your mother is not elevating her above all others in your kingdom, that is a human tendency not something actually taught in Scripture.
Israel is God's wife and the mother of the Messiah and as such if there is a queen of heaven it is the Hebrew nation, not just one woman.
