extra 12000 either end and down another 4 rows all the way round for the rest
How could they possibly put an extra 12,000 on each end? Just think about it. The ends don't even hold 12,000 at the moment, so you're suggesting they more than double the current stand capacity by adding another tier? That simply isn't possible.
You might be able to get an extra 6k at the very most at each end and that would be a HUGE job in terms of time, effort and money. And digging down (even just 4 rows) would take even more time, effort, and money. I don't envisage either of these things ever happening; it just isn't worth it.
And if the owners really have set 400m aside, they may as well build their very own brand new super-stadium from scratch.
