The one problem with modding seekers is that the damage seems to be hard coded. You can mod the missle mount to be 1/2 size and the mount says half damage but the seeker itself does normal damage (fun for strengthing missle races). Same for extending the ranges, the mount may go that far, but the actual seeker will not. At least as of 1.27b (but I could be wrong, these are just my observations)
