I think you are wrong about Dylan simply wanting to "make money", so to speak...You are right the Dylan dislikes the fact that so many claimed him to be more than he thought himself to be...he hadted to "Spokesman for a generation" crap.
His faith, however, was an is real...but he is private about it.
It is my view, that he simply loved/loves music...and he just wanted to make music that he liked...and he still does...that is HIS JOB...that is what he does...
As for Elvis, he did say that he thought Elvis did the best version of Tommorrow Is A Long Time.
Your view of Dylan's faith seems over-stated. He appears publicly (but not for publicity) at Jewish religious services, not Christian ones. His son Jess and son-in-law Peter Himmelman are active in Chabad.
I know personally some of the rabbis he's consulted in more recent years. None report his angling for any Jews for Jesus reconciliation.
You're right: He does view music as his job, above all else.
