To each his own. I will stick and align to the message and narrative of Paul and his context rather that grasping for straws as a sign of desperation to force or make Yeshua preexist by comparing it with his Father's work in Genesis 1:1 etc. You do as many others, a disservice to Paul's message regarding the church and its organization. You might try reading further into his message that reveals mor of what I've written.The echo of Genesis 1:26 in verse 15 does indeed harken back to the Creation narrative:
15 The Son is the image of the invisible God, the firstborn over all creation.
(Col 1:15) who is the image of the invisible God, the firstborn of all creation.
(Col 1:16) For in him were all things created, in the heavens and upon the earth, things visible and things invisible, whether thrones or dominions or principalities or powers. All things have been created on account of him and for him.
(Col 1:17) And he is superior to all things, and in him all things consist.
(Col 1:18) And he is the head of the body, the church, who is the beginning, the firstborn from the dead; so that in all things he might have the pre-eminence.
(Col 1:19) For it was the good pleasure of the Father that in him should all the fullness dwell,
(Col 1:20) and through him to reconcile all things to Himself, having made peace through the blood of his cross- yes, to reconcile all things through him, whether things upon the earth, or things in the heavens.
The Context of Paul’s Preaching
(Col 1:21) And you, being in time past alienated and enemies in your mind in your evil works,
(Col 1:22) yet now has he reconciled in the body of his flesh through death, to present you holy and without blemish and unreproveable before him.
(Col 1:23) If indeed you continue in the faith, grounded and steadfast, and not moved away from the hope of the gospel which you heard, which was preached to all creation under heaven. Of which I Paul was made a servant,
(Col 1:24) who now rejoice in my sufferings for you, and fill up that which is lacking of the afflictions of Christ in my flesh for his body's sake, which is the church.
(Col 1:25) Of which I was made a servant, according to the plan of God which was given me concerning you, to fulfil the word of God,
(Col 1:26) the mystery of which has been hid for ages and generations; but now has it been manifested to His saints,
(Col 1:27) to whom God was pleased to make known what is the riches of the glory of this mystery among the Gentiles- which is Christ in you, the hope of glory.
(Col 1:28) We proclaim him, encouraging every man and teaching every man in all wisdom, that we may present every man complete in Christ.
(Col 1:29) For this purpose I labour, striving according to his power, which works in me mightily.
