It can't be too hard. There's no doubt some issues - The NRL own the Sharks logo for licensing purposes (or something to that effect anyway), and the whole 'Superman' thing but surely nothing that can't be overcome. I'd suggest they're things you would have to research and resolve before presenting the final product to the Sharks though, they just don't have the staff numbers to be doing those sort of extras. There's your challenge. How keen are you?
