I didn't read through posts here, so I will just comment what you made in first one.

Mandatory ones:

1. Gem gens banned - of course, it should be part of CBM really.
2. Why? It's nothing about map size. It's about number of players and victory conditions. I wouldn't join 200 prov map with 30 players. 15 provs per player is what I like. And reasonable victory - 30-40% caps.
3. No way. You want what? Bless nations only games? You cannot play difficult res without serious rebalancing. I will never join a game like that. Playing normal nation would be unfun. Playing bless nation would feel like cheating.
4. Sure, CBM needs more extreme tweaks, but they won't be popular. Like more expensive Mind Hunts and tarts.
5. Nope. Low magic settings are simply boring. Put here instead a mod to ban overpowered sites [discount ones]. Even banning dwarven hammers would make more sense.

Optional ones are well... just for those that like that format. I like diplomacy, but I love RAND too. But I would stop playing Dominions if I had to play only RAND games.
