There was another topic about this same thing that was called "The Ultimate Gig" but as it seems that this one is more active, I'll copy and paste my post here.
Hook Me Up
One Wild Night
It's My Life
You Give Love A Bad Name
Undivided
Misunderstood
In These Arms
I'd Die For You
Burning For Love
The Distance
Joey
Mystery Train
Bounce
Captain Crash
Just Older
These Days
Neurotica
Encore 1:
Livin' On A Prayer
Born To Be My Baby (at this point I would be so scared that they are not going to play it

)
Encore 2:
Blood on Blood
I know this is never going to happen because I excluded Wanted (but I'd love to hear these songs played)! I also excluded classics like Bad Medicine, Lay Your Hands on Me, Sleep When I'm Dead but I think these songs are beginning to be overplayed.
If I could do whatever I want I would name at least 30 songs but I think 20 is more realistic.
