That good 'ol cultic book "Vine's Expository Dictionary of NT Words disagrees with your interpretation of this greek word. Vine's says about "adoption":
", "adoption of children" is a mistranslation and misleading. God does not "adopt" believers as children; they are begotten as such by His Holy Spirit through faith. "Adoption" is a term involving the dignity of the relationship of believers as sons; it is not a putting into the family by spiritual birth, but a putting into the position of sons. In Romans 8:23 the "adoption" of the believer is set forth as still future, as it there includes the redemption of the body, when the living will be changed and those who have fallen asleep will be raised. In Romans 9:4 "adoption" is spoken of as belonging to Israel, in accordance with the statement in Exodus 4:12 , "Israel is My Son." Cp. Hosea 11:1 . Israel was brought into a special relation with God, a collective relationship, not enjoyed by other nations, Deuteronomy 14:1 ; Jeremiah 31:9 , etc.

“greek expert and neither are you. So I’ll listen to the greek expert and not you if you don’t mind...”
From your own link:
“from huios, “a son,” and thesis, “a placing,” akin to tithemi, “to place,” signifies the place and condition of a son given to one to whom it does not naturally belong.”
And more:
“from huios, “a son,” and thesis, “a placing,” akin to tithemi, “to place,” signifies the place and condition of a son given to one to whom it does not naturally belong.”
The UCG and LDS position does not teach that we are only “placed into the position of sons,” but that we become literal gods after the ‘God Kind.”
Strong’s dictionary agrees:
uihothesia
hwee-oth-es-ee’-ah
From a presumed compound of G5207 and a derivative of G5087; the placing as a son, that is, adoption (figuratively Christian sonship in respect to God): - adoption (of children, of sons).
