Based on the system window being square, and considering the orbital path each planet would have to take, there could not be any outer planet. they would all have to be cramped towards the center. you would lose planet placement in the four corners, and they would have to follow a circular orbit (for the most part). Even if the orbit was not a epicycle, after not too many turns there would be planetary collisions. I just think trying to add that would/could add the potential for lots of bugs and hassels. If you want to add something, put some planets in those nebula systems, that only show up with the ship when they are on the same square. (yup, you would have to take many turns to explore one of those systems)
