I can tell you this is definitely not happening. The official rendering released when the move was announced is closer to what will happen.
For one, those picture windows aren't what is being built.
Secondly, the main entrance into the building is on Victoria, where the entrance to the Top of the Torch restaurant entrance was (at the southmost edge of the building on Victoria).
I'm not sure where that rendering came from, but it looks like some preliminary submission. It completely ignores the stage (photoshopped out) and what's with that hologram looking effect?
Further: signage was approved for a ticker to run the entire length of the West side of the building, for a digital screen facing the square (this rendering shows one that would face the side of the HNR building) and a multimedia tower on the torch portion.
