The dynamics within Gryffindor would be greatly affected. His friends like Ron and Hermione would be confused and sad. The Gryffindor house would lose one of its most iconic members, and there might be a power shift within the house. Other Gryffindors might feel less confident without Harry around.
The story could develop in a way that Harry goes through a period of self - discovery. Without the Gryffindor identity, he has to re - evaluate who he is.
