Seeing the bonuses drastically buffed would be interesting, but I feel some would be far better than others. Getting 3-9 free techs or policies would be insane! Meanwhile, I feel the 3-9 extra settlers would be a bit too much to handle (I.E. a good way for instantaneous unhappiness) and could actually backfire if a couple of your neighbors got #9, #10, or #11. All of that said, however, the more I think about it the more chaotic fun it sounds like it could turn out to be! It would just have to be something tested extensively, I'd think.
