Sure thing,
These are the mods I currently have installed (although I have modified some aspects of the mods to suit my desires)
Darthmod + Imperial Splendour - Best used together by creating your own tailor made mod from the two if you have the know-how
PIPmod
Smoke mod
Turns per year mod - if you like longer campaigns like me
Infua Music mod
Slower mod - Again best to tailor the mod to your own wants.
British Army graphics mod
Russian army graphics mod

Some aspects of "A Proper Empire" mod
I'm also using the devmode camera so that I can zoom way back from the battlefield and go inside buildings with the camera etc. Combined the mods I am using change almost every aspect of the game mechanics, unit costs, appearance, sounds, economy, unit balance, unit sizes, new unit types, weapon ranges, weapon damages, campaign movement costs, battle movement costs etc etc
