Maybe you're right. But, I bet that would be a tour focused on 'Senjutsu' AND 'Somewhere In Time'. As I have said once on this forum, there's some songs on 'Senjutsu' that can be linked to 'Somewhere In Time'. First of them : "Lost In A Lost World" that recalls "Stranger In A Strange Land" by its title. We also have "Days Of Future Past" which suggests something like a "Deja Vu". Finally, we have "The Time Machine" which refers to the theme of the entire 'Somewhere In Time' album : time.
So that could be logical to have a setlist based on 'Senjutsu' AND 'Somewhere In Time'. More precisely : the entire 'Senjutsu' live + 4/5 songs of 'Somewhere In Time' + 3/4 hit songs.
I guess this setlit could be this one (but I could be wrong) :
1) Senjutsu
2) Stratego
3) The Writing On The Wall
4) Lost In A Lost World
5) Days Of Future Past
6) The Time Machine
7) Darkest Hour
8) Death Of The Celts
9) The Parchment
10) Hell On Earth
11) Alexander The Great
12) Wasted Years
13) Déjà Vu
14) Stranger In A Strange Land
15) Caught Somewhere In Time
16) The Trooper
17) Run To The Hills
