The more I study Egyptology, the more I see it as a patriarch to Judaism, which is a patriarch to Christianity.
I'm not sure what you mean by 'patriarch'. I'd call Christianity a Jewish heresy that went on to grow much larger than its parent. (Mainly because it was no longer an exclusively ethnic religion.)
As for Egyptian religion, it probably did influence the ancient Hebrews in some ways. The Hebrews' myths also show interesting similarities with religious ideas from ancient Mesopotamia.
But I don't see the ancient Hebrew religion as branching off of either Egyptian or Mesopotamian religion in quite the way that Christianity branched off Judaism. It didn't adopt the earlier religions' scriptures into its own canon, nor did it imagine itself as somehow being the fulfillment of those religions. Judaism borrowed a great deal from its neighbors, while simultaneously holding them at arm's length and emphasizing its differences from them.
I wonder- how much information is out there on Egyptology as a religion-
There's a vast scholarly literature on ancient Egyptian religion. You probably couldn't read it all in a lifetime.
Here's the results of a Google search for 'egyptian religion' on .edu websites. (I specified .edu to emphasize academic opinion as opposed to cranks and 'new age' sites.)
is there enough to start it up again as an active religion?
Probably not. For one thing, much of our knowledge of earlier Egyptian religion comes from heiroglyphs preserved on their monumental tombs, which tells us a great deal about their culture's obsession with overcoming death, but tells us little about other everyday aspects of their religiosity.
But this is the internet and anything's possible. You can probably search and find groups out there who purport to follow ancient Egyptian religion.
