Another possibility MIGHT be to use a long exposure for the comet, then sometime during the photo of the comet, have your kids get into place and use a dim flash to briefly illuminate them, getting them in the picture too. You would have to put some effort into getting the flash just right. You would also have to be sure there was absolutely NO background behind the kids to mess up the picture (say a dark night, camara pointed above the horizon, kids standing on chairs, etc.)
