This looks like a good take on things, and the political and public-support aspects remind me of the VWA. It'd be nice to have another group to RP with on a number of characters, and like I said you seem to have some good ideas.
Following on from what Jamie said, there's no reason you can't make demands of Gallia and Bretonia. Opening up snubs to recruits would probably be the best way to do it, but limiting the Claymore spam is a plus indeed.
You might want to talk to Iris/Scout for some tips from her time leading the Underloch.
Other suggestions would be to do some Forum RP as tje Green Front. Some interaction with the LWB would be appreciated by Ktayn, there are plenty of Corsairs to talk to as well, and the Hogosha and possibly Kusari in general would be worth sending comms to. I'd also been looking to talk with some Gaians as the Colonials about Gallia, and some possible cooperation there.
