Hello and welcome from England. I like the idea, but it might be a lot easier, and much, much cheaper, to use a glass-fibre replica nose and prop, like the types used on some full-size museum exhibit replicas. Here's a pic of a full-size Spitfire MkIX replica, to give an idea of how good they are. The real thing, even a small part or prop, if able to find something, could cost a small fortune.
