Does the Father? Does the Holy Spirit? Are you actually suggesting a human body is required to be "God"?
You don't quite get what Col 2:9 is saying.
It is saying that every bit of what God consists of is inside the body of Jesus.
You likely think Jesus is a mere 6' tall man.
Fact is, Jesus, bodily, is an omnipresent quickening human spirit now.
This occured when Jesus' God raised him from the dead.
This is how all of Jesus' God fits inside of him today.
The alternative theology teaches that only the "qualities" of God and not ALL of God is inside Jesus.
It is a watered down version of Col 2:9.
