This has probably been an idea that has been kicked around, but what about a coaster based off of the 'tree surfing' in Tarzan?
It could be a stand up coaster, and maybe instead of having everyone facing forward they can face to the sides. So each rider you have its back to the other.
Then a 'catch' to the coaster could be that at certain parts the cart 'splits' (like the branches did in Tarzan) and you would be on an upward tilt.
Just another weird idea from your friendly neighborhood Starscream
