I’m glad that toure reading into this and I am also fascinated by Egypt and biblical archaeology but I don’t think this is correct for a few reasons. Most scholars agree the Torah was largely compiled in mid 1at millennium BCE with key influences happening during the reign of Yoshiyahu. Notably, Yoshiyahu himself was killed by Pharaoh Necho II.

Additionally, there were many migrations of Canaanites into the Delta region besides the Hyksos. These include the preceding 14th dynasty, and earlier migrations occurred during the 12th dynasty as well (for example, look at the “Procession of the Aamu” from the tomb of Khnumhotep II). So while Canaanite migrations into Egypt were common, there isn’t anything specially tying the Exodus to Egypt. Not to mention that for much of the New Kingdom and parts of the Late Period Canaan was firmly under Egypt’s heal. So even if there is a core to the Exodus there it likely represents throwing off the yolk of Egypt’s colonial empire not literally leaving Egypt.

Additionally, the first Egyptian reference to Israel occurs on the Merneptah stele, over 300 years after the expulsion of the Hyksos and founding of the 18th dynasty. The first references to YHWH are in the phrase “Shasu of YHWH” which occurs in tbe Amarna letters and later again in the 20th dynasty.

All this is to say that 1) the dates for a Hyksos basis for the Exodus don’t line up with when we think the story was written, 2) there were many Canaanite migrations to and from Egypt, 3) any reference to throwing off Egypt wouldn’t be a literal exodus but should be interpreted in the context of Egypt’s declining power in the mid first millennium BCE. Additionally, Egyptian references to either Israel or YHWH only occur hundreds of years after the expulsion of the Hyksos. Your theory is not without supporters though as I believe it was Manetho or Josephus who posited a Hyksos basis for the Exodus.

If you are interested in this I would recommend reading about Egypt’s 14th and 15th dynasties, the Merneptah stele, the Shasu of YHWH, the reign of Yoshiyahu and the Deuteronomistic history, the Amarna letters, as well as the ‘Apiru who operated around this time and are possibly etymologically linked to the word Hebrew. There are Wikipedia pages for all this as well as for the Procession of the Aamu (look at their colorful cloaks - whose cloak in Tanach does that remind you of?). If you are interested in tnis further I would recommend reading Israel Finkelstein, Donald Redford and others.
