I could see them being used to recreate concert experiences, imagine being able to see a reasonable facsimile of a Beatles concert, with figures that look and move just like the real thing.
That’s actually a pretty neat idea - I might even pay money to see a high-quality Keith Moon or Jimi Hendrix. It’s not too hard to imagine a time in which you could purchase a system that allows you to assemble your own super group of vintage rock stars (I think I’ll call mine “The Dead 27’s”).
