I'd go for a live tour of the Alton Towers themes live such as Nemesis and Hex which would all sound incredible, but what about giving the Haunted House and Toyland Tours themes to a live environment? That would be amazing too especially the former would really sound intense live.
A live version of Oblivion and Air would sound, uh, interesting live but yeah, I'd love as part of Nemesis' grand reopening event in the evening with it's theme played by a live band with impressive lighting taking place...would be the best opening of a ride Alton Towers would have done which honestly given their track record of opening rides isn't saying much.
