Actually, form an engineering standpoint, the Dome would work for serving as a shell for an intimate 25,000 seat soccer stadium. Back in its hey day, the Dome used to seat 42,000 when one end of the stadium was left open which made room for the scorebaord spectacular. If you subtract the other endzone, you easily shrink capacity to the nieghborhood of 30,000 or less. Open ended soccer stadiums are the popular designs for the MLS anyways. To further shrink capacity, the interior would need to be gutted and the concourses would need to be enlargerd, which would push the seating deck closer to the pitch. Overall, this would eliminate sections in the seating bowls design which could get you to the 25,000 mark. What I would like to see done is for the the entire reliant campus be sectioned off into three rectulangular blocks. One for Reliant Center, the middle for stadiums, and the last one for parking. the Astrohall needs to be replaced by a Parking garage structure to serve soccer. The parking lot east of the Dome needs to be raised for in favor of a retractable soccer pitch that could move in and out of the Dome to make it more multipurpose. The Dome's seating bowl needs to be as multipurpose as the Saitima Super Arena in Japan, which can change form a 40,000 seat soccer stadium to a 5,000 seat concert venue in the blink of an eye. And last but not least...on the North end of the Dome that faces Reliant center, an air conditioned, sheltered walk way with moveable pathways like you find in airports needs to be built to connect Reliant Stadium and the Dome to the light rail line to make it more attractable to use for commuters. No one likes trudging across barron parking lots in the middle of the night to catch a train....wake up Metro. This needs to be done.....nuff said.
