I am a little scattered in the head to add any theological insights, but i can add something of directly related interest.
You should look into the Ethiopian Church. They have a very strong connexion between the Blessed Mother and the Ark of the Covenant and Noe’s Ark. Their temples contain representations of both. Their Tabernacles are in the shape of a boat, according to the description in Genesis. Also, they have replicas of the Talbot, the Ark of the Covenant that are used in worship. Both of these have images of teh Mother of God painted on the top or sides, showing the connexion between her, and the bearer of the Law, the bearer of the Covenant, and the Ark of Salvation.
In Christ,
Adam
