My vote is to leave it, it's beautiful just the way it is. If there was only 1 that was going the wrong direction then you would have a problem but the way you have it, it looks planned that way. The quilt police are not coming to your house, finish it and enjoy. If anyone says that some of your lighthouses are going in different directions, just say "I know, it was very difficult to do it that way but I was able to figure it out." :)
