Why not just turn the seizmic coaster track a quarter turn and u have a sitdown/floorless & a inverted sharing the track? Or use Intamin track. Two problems though, heartlines & supports!
Another idea is to have the back of rows/seats connected to floorless chassis via a car type axle inline with track & some ingenious mechanism to control the rotating. This will allow the seats to rotate to Floorless/Inverted or even Sidewinder position depending whether the track is in F/I/S orientation!! Imagine a Cobra Roll which is half F, half I! Or even a fake zero-g roll, i.e. cars spin 360 over a camelback. Try 720 degs for the not-of-faint hearted! Or a fake curve!
