They key objective of this question is to identify the Pharaoh of the exodus. A popular candidate is Thutmose II who ruled briefly before Akhenaten. Is it possible that Akhenaten got the idea to synthesise the pantheon with monotheism from the events that occured to one of the Pharaohs that ruled before him? And if not Thutmose II, then who?
Short answer, no.
Longer answer, while it is very probable that a group of individuals, who had been held in slavery or sub par conditions in Egypt, later migrated to Palestine and helped form what would become the Israelites, the story in the Biblical account just isn’t accurate. There was most likely no mass slavery of proto-Israelites, and no mass exodus.
There is debate as to the legitimacy of an Egyptian group at all, but most mainstream scholarship on the origins of the Jewish people argue that what the exodus shows (besides the theological implications) is the remembering of one small group that migrated to Palestine and eventually mixed with other groups, one probably from the Mesopotamia region and another that split off of the Canaanites. These multiple groups merged, and eventually worked to create a unified national epic that contained historical nuggets of all three.
Even if we accepted a mass migration, the Hebrews at that time weren’t really monotheistic. They practiced a form of polytheism called henotheism. And to be fair, some of the early Hebrews also worshipped multiple gods.
A better connection with monotheism would have been Zoroastrianism, which was a dominant force in Persia (or became such. The religion had an origin further back then). There may have been some influence with Egypt but I think that may all be reaching for a solution that isn’t needed.
The easiest answer is that a monotheistic view isn’t that much of a stretch from polytheism, especially when you place politics with it. It’s an easy way that one can unify a country even more, or it can blow up in your face.
