This is only my first reaction and because I haven't had time to think about it, I may be wrong, perhaps others will comment.

It would seem that you are spiritualizing the texts, especially by equating the Son with the sun. Other than the fact that the Son created the sun (John 1:1-3), I see no reason to spiritual this.
Also, though I have read a fair amount on this topic, if I understand you properly, I have never read anybody else say what you did.
