A very similar scene is in Epistle of the Apostles (140-50CE)
3 In God, the Lord, the Son of God, do we believe, that he is the word become flesh: that of Mary the holy virgin he took a body, begotten of the Holy Ghost, not of the will (lust) of the flesh, but by the will of God: that he was wrapped in swaddling clothes in Bethlehem and made manifest, and grew up and came to ripe age, when also we beheld
13 Now that which he revealed unto us is this, which he spake: It came to pass when I was about . . . to come hither from the Father of all things, and passed through the heavens, then did I put on the wisdom of the Father, and I put on the power of his might. I was in heaven, and I passed by the archangels and the angels in their likeness, like as if I were one of them, among the princedoms and powers. I passed through them because I possessed the wisdom of him that had sent me. Now the chief captain of the angels, [is] Michael, and Gabriel and Uriel and Raphael followed me unto the fifth firmament . . . , for they thought in their heart that I was one of them; such power was given me of my Father. And on that day did I adorn the archangels with a wonderful voice . . . , so that they should go unto the altar of the Father and serve and fulfil the ministry until I should return unto him. And so wrought I the likeness by my wisdom; for I became all things in all, that I might praise the dispensation of the Father and fulfil the glory of him that sent me . . . and return unto him. . . .
14 For ye know that the angel Gabriel brought the message unto Mary. And we answered: Yea, Lord. He answered and said unto us: Remember ye not, then, that I said unto you a little while ago: I became an angel among the angels, and I became all things in all? We said unto him: Yea, Lord. Then answered he and said unto us: On that day whereon I took the form of the angel Gabriel, I appeared unto Mary and spake with her. Her heart accepted me, and she believed . . . , and I formed myself and entered into her body. I became flesh, for I alone was a minister unto myself in that which concerned Mary . . . in the appearance of the shape of an angel. For so must I needs . . . do. Thereafter did I return to my Father . . .
In the Ascension of Isaiah, the Christ descends through the levels of heaven undetected by taking on the forms of the angels in each level. Eventually he takes a body that appears human, is killed, frees those in sheol and returns triumphantly. There is a large section of obvious harmonizing Christian addition detailing his birth and time on earth. Now, here in this Epistle of the Apostles version Christ is explicitly identifying as the angel Gabriel (or impersonating him). He takes on any form able to become anyone. It's all an interesting study worthy of more time than I have.
