We already have to use 2 decks on some maps with 9 players. Our system only supports up to 4 decks.
Also, the "resident cyberbrains" also care about user experience, and you need something like colours to make it possible to easily distinguish which territory belongs to which. If we did it with numbers, you'd need to look at every single territory individually to find the number and thus who it belongs to. This probably makes the game unplayable, because it would be near impossible to get a good feel about who is powerful.
