How can I possibly be truly right with God, even knowing Him directly, while not knowing who Jesus is?
You can't!:
John 14:6- "Jesus said to him, 'I am the way, and the truth, and the life; no one comes to the Father but through Me."
Matt. 11:27- "All things have been handed over to Me by My Father; and no one knows the Son except the Father; nor does anyone know the Father except the Son, and anyone to whom the Son wills to reveal Him."
John 17:20-26
20 "I do not ask on behalf of these alone, but for those also who believe in Me through their word;
21 that they may all be one; even as You, Father, are in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me.
22 "The glory which You have given Me I have given to them, that they may be one, just as We are one;
23 I in them and You in Me, that they may be perfected in unity, so that the world may know that You sent Me, and loved them, even as You have loved Me.
24 "Father, I desire that they also, whom You have given Me, be with Me where I am, so that they may see My glory which You have given Me, for You loved Me before the foundation of the world.
25 "O righteous Father, although the world has not known You, yet I have known You; and these have known that You sent Me;
26 and I have made Your name known to them, and will make it known, so that the love with which You loved Me may be in them, and I in them."
Mark 10:32-33
32 "Therefore everyone who confesses Me before men, I will also confess him before My Father who is in heaven.
33 "But whoever denies Me before men, I will also deny him before My Father who is in heaven."

There is in fact no place or need for Christ in my experience of God.
Then the "god" you are expereincing is not the God of Scripture, for, as I mentioned earlier, Heb. 1:1-2 says:
1 God, after He spoke long ago to the fathers in the prophets in many portions and in many ways,
2 in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world.
Christ is our only hope. His blood is our only plea. His righteousness is our only covering in the sight of a just and holy God.
Rom. 3:21-26
21 But now apart from the Law the righteousness of God has been manifested, being witnessed by the Law and the Prophets,
22 even the righteousness of God through faith in Jesus Christ for all those who believe; for there is no distinction;
23 for all have sinned and fall short of the glory of God,
24 being justified as a gift by His grace through the redemption which is in Christ Jesus;
25 whom God displayed publicly as a propitiation in His blood through faith. This was to demonstrate His righteousness, because in the forbearance of God He passed over the sins previously committed;
26 for the demonstration, I say, of His righteousness at the present time, so that He would be just and the justifier of the one who has faith in Jesus.
1 Timothy 2:5- "For there is one God, and one mediator also between God and men, the man Christ Jesus"
Heb. 9:15- "For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the transgressions that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance."
