I think I'd have prefered (or would have found it more intereseting) if you chose a (current or former) Premier League player from each country/region for their respective banners. For some regions or countries you wouldnt possibly find a player, you could have chosen a random player then.
For Kanto you would have to choose the super-obscure Kazuyuki Toda who made 4 appearances for the Spurs in 2003, when he was there on loan
Anyway, still a very charming approach you came up with and a great promotion for Newcastle
