They wouldn't necessarily have to add to the seating capacity to bowl it. There's no way with Vanier there that we could physically duplicate the bowl seating of the South end zone, but they could at least bowl it around in a smaller incarnation and make it look way more symmetrical and legit than what we have now in the End Zone Fun Zone. It would suck to have to pour concrete over something we just constructed 5 years ago or whatever, but as it is now, it looks uneven and pretty weird/bushleague-y. The Fung Shuieiiie of the stadium is way off. Would look way better if it were bowled to mimic the SEZ, with the same angles and grades and everything, just going up 17 rows or whatever instead of 45, and it wouldn't add a bunch more empty seats. And of course there would have to be badass tunnels cut out of the stands for the teams to walk through and we could even get FOG MACHINES!!!
Keep in mind that I realize this will never happen, but it would look way better than the weirdness that is there now.
