But you are just repeating your claim.συ εἶ τῇ κεφαλῇ παχύς... It is simply used as God without respect to Father, Son or Holy Spirit.
I am asking you a simple yes or no clarifying question concerning your (weird) claim:
With bold above are you saying that “God” in John 1:1b is a single person, albeit not defined as Father, Son or Holy Spirit ? Yes or No ?
