well unless im missing something these textures are too small and impractical and they don't appear to be the correct dimensions for use in battlefield.
I think you should actually try some modding of the game and then you will start to understand where you might be able to help.
That would be very useful rather than random thoughts... If modding the game and this site interests you then try to mod something.. it would be more interesting to see a screenshot of an object you have modded with your textures for example.. rather than just posting kinda random tiny images.
go and mod.. learn about the game.. understand what kind of image sizes and formats are suitable..
