In terms of location sure but the current design is entirely different from Arena 2000 so doubt it’s easy
I'd say the structure of the 3 main bowl stands (with 90% certainty) is not designed to allow an easy extension.
I could be wrong, but the projecting support structures which suspend the roof also provide support and lateral restraint to the main columns and beams which hold up the stands themselves. So just to raise the roof level you're having to do major temporary works to support the stands.
Those support structures also go through the external concourse walls as their foundations are within the building footprint, so if they weren't future-proofed you'd have to take down large areas of the current facade and put new foundations down inside.
It could be cheaper to start again with those, if we did 1 end stand for example you might choose to remove it, shallow out the lower tier before putting a second above.
Not sure on the corporate side, suppose its not impossible they built the balcony with something in mind.
Might be possible to push the white clad wall back and the upper tier become deeper, it would have to go closer to the roof relative to the main stands though.
However as there's support for the balcony at the moment, its potentially more possible to reinforce the structure there.
As
@Hutch11 said though, the cost would be enormous so we're years of sell-outs and a promotion away from even considering it.
Lets not get ahead of ourselves
