In Luke 1:35, does the Power of God overshadowing Mary describe the incarnation—the Son of God merging into Mary to become the Son of Man?

Does the Power of the Most High overshadowing or enveloping Mary describe the incarnation of the Son of God, his transformation from divinity to mortality? Luke 1:35 ESV > And the angel answered her, “The Holy Spirit will come upon you, and > **the power of the Most High will overshadow you**; therefore the child to > be born will be called holy—the Son of God. The Son is identified as the "Power of God" and the Wisdom of God in 1 Corinthians 1:24 > but to those who are called, both Jews and Greeks, **Christ the power > of God** and *the wisdom* of God. The Wisdom of God existed with God from the beginning according to Proverbs 8:30 > Then **I was a skilled craftsman at his side**, and his delight day by > day, rejoicing always in his presence. The Wisdom of God is also the Word of God according to John 1:1 > **In the beginning was the Word, and the Word was with God**, and the Word > was divine. The Son became flesh according to John 1:14 > And **the Word became flesh and dwelt among us**, and we have seen his > glory, glory as of the only Son from the Father, full of grace and > truth. The Son was at the Father's side during creation, and the Son became flesh at his conception by the Holy Spirit. Again my question is, Does Luke 1:35 imply that the Son pre-existed his human incarnation as a divine personage, and did this personage overshadow Mary at the spiritual conception of Jesus to undergo the kenosis and incarnate into flesh as described in Philippians 2:6?
