No, ProfLogic.
I don't think you have study Egyptian religion/mythology at all. The Egyptians were actually tolerant to other religions and are very willing to adopt other deities. They had adopted Canaanite, Syrian and Babylonian deities into their own religions, like Baal, Anat, Astarte, Ishtar, and many more (but which I can't think straight at the moment; I am suffering from dizziness and the flu, so forgive me if I my post don't make sense in some areas).
The only exception is at the time of Akhenaten (18th dynasty king) and his monotheism of Aten; this was the only time they had religious persecution. Religious persecution was completely unheard of before then. And even after the people returned to the old polytheistic religion, they still continued to worship Aten, even after Akhenaten's death.
The 19th and 20th dynasty adopted a lot of foreign deities, so the Egyptian kings would not have hesitate to adopt something like the all-powerful Hebrew God, because it would have suited them quite well to make a myth that the Hebrew God had given them the divine right to rule over Egypt, like their native sovereign gods had (eg. Re and Horus). They had readily adopted the Greek gods, when the Macedonians arrived.
Unlike Judaism and other monotheism, ancient Egypt is very willing to adopt as many gods as they like. There were no rules of not accepting a foreign god, because Egyptian religion has no creed and no dogma.
That's why I don't think the Exodus display a realistic portrayal of Egyptian kings in regarding to native and foreign religion.
The Hyksos brought with them the Canaanite goddess Anat with them, and they still worshipped her in the 19th and 20th dynasties (New Kingdom). Sorry, ProfLogic, but I don't buy your assertion about wiping out another foreign religion.
And if they had tried to get rid of the Hyksos without learning from them, they would have undoubtedly failed. The Hyksos brought new technology with them, so without adopting them, the Hyksos would have continued to be the Egyptian masters.
And I still don't think the Hyksos and Hebrews are connected. The Hebrews knew nothing about the chariots.
