I think it would be an interesting submod. There are other more reliable sources about that era and those could be used. But it would require a team of researchers, modellers, script writers...

BTW, I have read a book about about Hittites recently and the first people who discovered them took info from the Bible which told about "Heteans" (not sure about English version, original is Hittim). I wouldn't underestimate any religious book or mythology.
