Yeah, a four seater would be nice, but I don't think it's physically possible for the very reason you mentioned. Something I wanted to point out about the track color and possible support color. The closest analogue we've been given is Taron which has a grey-black track color and supports. This helps the coaster structure blend into the rockwork around the ride. To me, seeing black track show up makes my mind want to confirm a lot more rockwork than some expect.
