No. The Word in 1John 1:1-3 is John writing about what the Word literally is and what John said about the Word in John 1 is poetic in Hebrew fashion and there is nothing to capitalize about it. John is writing based on the precedent that the word of God is personified in Hebrew poetry, but not a literal person.
The word of God personified in Hebrew poetry:
Psalm 33:6
By the word of the LORD the heavens were made, their starry host by the breath of his mouth.
Psalm 107:20
He sent out his word and healed them; he rescued them from the grave.
Psalm 147:15
He sends his command to the earth; his word runs swiftly.
The word of God has divine attributes, but is not God:
Isaiah 55:10-11
“For as the rain and the snow come down from heaven,
And do not return there without watering the earth
And making it bear and sprout,
And furnishing seed to the sower and bread to the eater;
So will My word be which goes forth from My mouth;
It will not return to Me empty,
Without accomplishing what I desire,
And without succeeding in the matter for which I sent it.
Isaiah 40:8
The grass withers and the flowers fall, but the word of our God endures forever.”
Psalm 119:105
Your word is a lamp for my feet, a light on my path.
It would be extremely difficult to make your "the word is god" in a literal sense work. The entire body of Scripture about the word of God contradicts your premise. Not only is there 1John 1:1-3 that proves your theology about God as false, but when Jesus and the Word of God are used in close proximity of one another, they are not the same person or thing. They are entirely distinct.
Revelation 1:2
who testifies to everything he saw. This is the word of God and the testimony of Jesus Christ.
Revelation 1:9
I, John, your brother and partner in the tribulation and kingdom and perseverance that are in Jesus, was on the island of Patmos because of the word of God and my testimony about Jesus.
Revelation 20:4
Then I saw the thrones, and those seated on them had been given authority to judge. And I saw the souls of those who had been beheaded for their testimony of Jesus and for the word of God, and those who had not worshiped the beast or its image and had not received its mark on their foreheads or hands. And they came to life and reigned with Christ for a thousand years.
