Apart from being improbably long especially if you mean the whole of SR that's not bad and strikes the sort of fantasy/realistic balance you aimed for.
Is it improbably long though? I wouldn't be much longer than their 2007 shows, by my calculation it would only take a bit over 2 and a half hours, so you might have to trim some songs out but I don't reckon many. I guess you also have to take into account the fact that they are all 13 years older! And yes, I left of a few which I'm sure they will play, for example "I Can't Dance" given that Mike heaps and lavishes an outpouring of praise upon that damned song every chance he gets! I actually really like my idea of them doing Fountain of Salmacis - it's their second best song, the vocals are manageable and it would be a great surprise for their fans.
