I noticed some people have mentioned a tilting track of some sort.
What if...
1: The train leaves the station and enters a trick track.
2: The track tips to the side, Winjas Force style, but to 180 degrees.
3: Train rolls down into a half loop style element
4: When train has reached the bottom it is then the right way around again.
Not the greatest image, but you get the idea. The train is still on the first segment. Some effects happen, and the track spins upside down. The brakes then release and the train rolls in upside down, following the red arrow, before scooping out and heading to the first lift.
Size depending they might even be able to cram another roll in between this and the lift. That'd give us what... 11 inversions? That'd make it joint first with another coaster opening in 2013 on the inversion list, according to RCDB. I'm guessing there's also be some kind of worlds first in the trick track...
Obviously, I have no idea how the forces would work on this. I doubt it'd be impossible though. A similar idea works on G-Force at Drayton, the only difference is this starts at the top, rather than using a chain lift to get to it. Just thinking off ideas which other people have suggested
