Concerning music, I hardly expect a big record company to say much. Either they don't reply (very likely) or they say no. Well, that is my experience.
But let's discuss your game ideas instead. I don't think you need to worry about names or art. Names can be slightly altered for the final version (like Fans Of Stargate, would clearly state both inspiration and that it is not part of the original) and the graphics can be redrawn a bit if it seems vital.
