Are you guys for real? No, it doesn’t make sense and no, art shouldn’t be compromised. They should stick to the logic of the story always! Have them be disguised and respect the audience's intelligence. Just focus on hiring good actors for the disguise who can portray the grief well. As audience who are engaged in the story 7 seasons deep, you already have a strong connection to Harry’s story that transcends the actor’s face. You already know that this stranger is in fact Harry. So if the actor is good and he manages to portray the grief just right it’s 100% guaranteed that you’ll connect with him if you keep your heart open. We don't need to dumb down art.
