I'm afraid not. I put Good Omens in the second or third tier of stories that it is hard to find a writer, aside from the original, that writes a close enough match to meet my tastes. It is well written or self contained enough that I have trouble finding anything else in that space interesting.
Anyway, I know Moczo and PurpleMoon3 have some Good Omens fics.
