Xerxes/TMOI/Alan etc - pre-empting any studies (I know we've just got to wait and see now), and height issues aside, do we have any idea if it would be physically practical to keep the Main Stand and Anfield Rd end as they are, remove the roofs and add a new tier on each stand? Only asking because I've seen it done in Spain at El Molinon (Sporting Gijon), the oldest ground in Spain, and it looks fantastic now. Was sat in there many times whilst the new tier was going up above our heads. Didn't take long either, a matter of months.
If it was possible to do the same at Anfield, it would surely have several advantages over demolision and re-building the stands (cost, less disruption/loss of revenue, and also it would keep the current capacity of the existing Main Stand which I've read on other threads is relatively high due to the compact seating).
Any ideas if it's physically possible to start with? (P.S. "I don't know" is an acceptable answer!)
