I'll join in to say the proposed settings are a very good way to lead to a disaster.
With that many provinces and vanilla, if you get many players, I can predict an end-game with so many clams, fetishes and blood stones that the winners will spend an hour just checking the gems on scouts. People will get bored and leave because it's not 1 hour you will need to play a game with these settings. I already need 1 hour to play a game with maybe 10 provinces when I'm at war. When you have 80 provinces and a lab full every turn with forging clams, armor, swords, blood stones etc., you will really wish you had piacked a smaller scale game because frankly playing 2 games at 10/15 provinces per player doesn't take much more time than 1 game with 25 but is way more fun.
