Aww Hagrids hearts in the right place, and all Gryffindors 爱情 him so I think they wouldnt mind, they know Hagrid and they can trust him, but I knowit seems strange but Hagrids lovely. Perhaps Percy Weasley 或者 someone comes back to become head of Gryffindor house, because he was prefect and hes worked at the ministry so he has a lot of experience of being a leader.
McGonagall never became headmistress she remained as Head of Gryffindor and Transfiguration teacher until at least 2008 when Tales of Beedle the Bard wa spublished and it's mentioned she was still transfiguration teacher. She did retire sometime between 2009-2017 it is never mentioned who took up the role as Head of Gryffindor but I like to assume it would be Neville Longbottom considering he started teaching Herbology at Hogwarts some time after the 秒 war.
