I am not sure what the laws are Shogun but the UFC has venues now in Canada and all over Europe and there is talk about Mexico City(God help us) and so there are ways to get around such laws if they are applicable. As far as the diminshed status of certain fighters who would lose, that's a concern but the money that would be raised, the attention brought to the sport and the sheer entertainment value of such a tournament would far outweigh anything negative that might happen. By the way, this is the kind of tournament that I would like to see happen every four years or so and not something regular.
