Hmmm maybe I could help you with the Mod.
Before SINS I modded Empire at war.... 3 Years....
I was a member of the stargatemodding group. Maybe some Eaw-players remember.
There my positions were Particlecreator, Projectilemaker and Community Stuff (such as Wallpaper, Avatars, Design.....).
And the most important: I'm a big Stargate Fan. I can not say, that I watched every single Episode but nearly all. Also, I like SG-1 more than Atlantis (Although I watched the movie

), actually I don't like the Wraith.

Well back to topic. I really wanna help you, but I think you create too much ships on your own. Of course it's good to make your fantasy become real in Soase. I know many guys, who made their own ships too. But first, they integrated REAL Stargate ships into their mod (A mod, built up with the original Stargate Mod...).
Well I hope you make more real Stargate ships. That's all I want to say.
However, I started modding SINS a week ago, and it's very similar to eaw's xml base.
Well I'm not going to code much but the particle System needs to be more discovered, I think. There are great possibilities!
Uhm, I wrote too much. I hope you understood everything, I'm from germany, so please ignore my mistakes.

Some works. But these are Small works, maybe I'm going to make a new SINS cover. With Stargate Ships, of course. ^^
