Is it possible to add these things in to civ5

[aTobin]

There is a lot of essential things that didn't make it from Civ4 to civ5:
Health/sickness
Happines induvidual per city
Cottages-Hamlets-Towns
Espionage
Culture/etnic influence per tile and the possibility to cultural capture other civilizations tiles.
Religion
Electricity
Civics
Vassal-states
Graphs and the civilization score list
Bombing improvements
Growth, Productions, cutlure, great general bars
Hurry production

This is the things i miss most from Civ4. Is it possible for the modding community to mod these things into the game?

It requires the source code. We'll need to wait.
