It's basically entirely incompatible. Makes your game crash when trying to launch the campaign. I'd play normal, then with BC Supermod, then with the Single Player Mod when it comes out, and while you wait, play with Kobayashi Maru in Quick Battle to pass the time. It helps to keep a separate install for each mod - copy-pasting the unmodded BC several times and renaming the folder (BCKM, BCSM, etc.) helps. I'd install any other ship specific and such types of mods to the Kobayashi Maru folder. Of course if you want to play Kobayashi Maru multiplayer, don't install anything other than the latest KM. When I actually played the game, I had several folders: Unmodded, Supermod, Kobayashi Maru unmodded, Kobayashi Maru modded, each being larger than the last. I believe my KM Modded install totaled between 20 and 30 gigs when I was through.
