I like the package. It could be even more minimalistic and naturally more puffy, but it certainly is more balanced than original and gives also some new feats to try out so I wouldn't mind playing a game with it. Are you planning to include also bug fixes to this?
Concerning Espionage I would suggest mostly the approach of RBmod:
* Remove civic/religion switch missions
* Double the price of other missions (You could also use some effort to fine tune it more, but this is the simplest way)
* Remove counter-espionage mission
* Remove discounts based on religion (other discounts are ok e.g. the one based on OB is good since you can easily affect on it)
