Just wanted to say what your doing is great. I was starting my own mod but this mod has most of what i want in a mod. As a suggestion would you add in orcs? I can send the basic orc creature and civ I have made if you want to add them to your mod.
Bog trolls are basically my version of Orcs, but much larger. They draw pretty heavily from the Warhammer universe, but use more traditionally orcish graphics (jet black skin and horns). That being said, I have set up LFR so that it does not conflict with other civilization mods, so you're free to put Fortress Defense or your own civilization in on top of it without causing any technical problems.
I am a bit fed up with civilizations at the moment, to be completely honest. They're very fun to make, but a nightmare to try to balance, especially when you start getting more than 5 or 6 of them. My current stand on civilizations is best summed up as follows.
-LFR has all of the civilizations it needs to utilize its current features. As new features become possible, new civilizations will be looked into as an option for exploring them.
-LFR's current number of (mostly) balanced civilizations is restricted by hard limits on inter-civilization relations and my desire to make LFR challenging, but not as overwhelming as the constant attacking armies of Fortress Defense. If these limits are expanded, civilization development will also follow. The "military arc" that Toady has planned will likely factor into this, but it is too early to make any serious speculation. A token to force hostilities between specific entities would allow some relief from the pressure of constant siege by forcing armies to fight each other when both arrive on your doorstep, but this is currently impossible to do.
-The (currently theoretical) diplomatic tokens would allow some previously impossible or horribly unbalanced features, such as a civilization of extreme power that is hostile to everyone (the "common enemy" or "greater evil"), or a civilization of "peacekeepers."
If, however, you sent me your Orc creature raws, I would be more than happy to include the creature and create graphics for it. It would not be a full civilization as of yet, but it would be complete and usable in the arena. Credit, of course, will be given.

Trivia: There is actually a language file for the originally planned "extreme power" civilization included as part of LFR, but it is not used by any current civilizations. This civilization was meant to be based in the deserts/savannahs and attacked in vast numbers. Though the original idea was shelved pending further developments, occassionally a world may generate with a name taken from this language file. If the tokens necessary for it are developed, I will revisit this concept and consider others.
