I don't see how Tony could ever not know that Howard was born Jewish and, since he probably failed to convert to anything else, remained Jewish until he died. This is a non-starter point for me. He knew Howard was a secular Jew, he knew Maria was (presumably) not, and that by the laws of Judaism, Tony himself was not considered Jewish. He doesn't care.

I don't see Tony ever being interested in faith-qua-faith at all, to be honest. He's a strong disbeliever in the occult in general. He's not going to be curious about the God and laws of his forefathers because it's all hocus-pocus. It's not a matter of being "geeky" or not; geeks are as unique as everyone else and not everyone is required to follow the stereotypes. Tony is a builder and a pragmatist and a futurist and he doesn't like to consider the past at all. He's not interested in his own or in his father's or in the magic building blocks of religion. He could not care less about shatnez or its origins -- that's for the social sciences and their storytelling.

Also, his prime motivating factor in almost every single thing he's ever done is to disavow everything Howard did and stood for, to stand on his own merits (or lack thereof) and be his own man. Going looking at religion, let alone his father's religion, is not something I see as following on that path because the whole animating factor of a religion is submission (to laws, to gods, to the more learned, etc.).

This is not to discount your experiences or say that they don't matter. They're yours and thus they do. But I don't see Tony as interested in that kind of self-examination. YMMV.
