In a general way, that Baltic Homer model resembles Black Athena, British Israelism, and a number of other drifts, including some cults (in Michigan, we had “The Black Hebrew Israelite Jews”, for example). Plenty was going on anywhere that humans lived, but writing either didn’t exist or didn’t survive (or barely did).

Specific to the Baltic Homer model, it’s not credible imho to regard the Odyssey as a documentary anyway. Unlike the Iliad, which clearly has a basis in events in the area where the story is set, the Odyssey is just a high seas adventure story, older but not dissimilar to the Voyages of Sinbad or the ancient Greeks’ other epic, the Argosy.
The Odyssey comes across as a romantic novel of the classical times, and I’d not be surprised at all to learn that Samuel Butler’s “Authoress of the Odyssey” is close to be the correct approach.
Women for Children, Boys for love. This seems to be a recurring theme among the Greeks, was Homer a Poof?
