Yeah list all the equipment you plan to use and that will give a lot better idea of what possible combinations are possible. Just to be clear you want a pair of midbasses in each door a midrange in kicks and possibly two pairs of tweeters? If you run one mid and one midbass in the door with another mid in a kick and two pairs of tweeters its going to be a huge pain to tune for many reasons. It does not sound like a good place to start.

You could highpass at say 600 hz or so and then go to a passive to the mids and tweeters. You would not be able to add a second set of tweeters unless the x over is designed for it though.
