I would love to help with this, call me in a few months as I'm getting better at modeling skills. To chaos with it, if you send me some good modeling quality photos, I can start the LOD4 right now. no promises on when I'll be done though, I'm not a professional modeler by any reach. My prefrence is Tau/Ork/Necron in that order.
Also, BFG (battle fleet gothic) does use fighters, even if it simplifies them in the extream. I could quite easely see the player being a member of an elite squadron of Imperial/(dark)eldar/Tau/Orc/Necron/(Chaos)Space Marrine/Tyrianid fighters. In point of fact, a few months ago, I went looking for a mod for this.
Just need to remember to start small, and not to get hungup on the unimportant details like proper ship modles, voice acting, or perfict features. I, and I asume some outher people, would be satisfied with placeholders in the missions untell modles could be compleated.
