Full Conversion/Extended Endgame Modpacks -- Seeking Advice

Hey everyone,

Longtime Civ4 player and mod user, have now (I know, I know -- late to the party) played about 50 hours of vanilla Civ5 and am looking for some full conversion mods -- and advice.

I was a crazy huge fan of Fall From Heaven 2 and its associated modmods. Looking for something of similar quality, though it doesn't have to be fantasy-set.

I've played Faerun and I did like it but it just didn't click with me like FFH2 did.

I also played the LOTR mod and enjoyed it but it's a bit too static for my liking.

Looking for something with the following qualities:

1) Total conversion (I don't want to muck around with 20 mods if I don't have to)
2) Extended endgame is a must: I play on max difficulty on the biggest maps possible, and like an elaborate and slow-paced game (typically with elimination victories)
3) Can be fantasy or science fiction setting
4) Some improvements to economy and diplomacy would be nice (I care a lot less about combat)

Thanks guys!

Bump? Any suggestions?

I think Faerun is the best generic one, even though it is not finished yet (or ever).
The LotR mod from ispanets (sp?) is one of my favorite specific mods (Zwei's Renaissance Era Revised as a close second).
