I'd be all for renovating McMahon, I thought there was a study that came out that said it wouldn't make sense on a dollars basis given the age and concrete construction of the stadium though.
But as long as we're imagining renovation ideas, I'd agree with others that the concourses should built out and expanded. A balcony could definitely be built on the Western stands, to add bathrooms and space. When I went to watch the Rose Bowl I found it interesting that the concourses were all outside the actual stadium but inside the gates, so even though Calgary doesn't share Pasadena's weather we could still make that work here.
Another thing we could add is something like the West Jet Flight deck in Toronto for jays games, a standing area patio with tables and rails where people can come and go as they please. There's a dedicated fanbase of older CFL fans, the way the stamps should go is to entice more 20-30 hipster people to enjoy alcohol and football in the sun, the westjet flight deck is great for that. I they could take out some high-center bleachers and put a patio there, or on my own personal pipedream of a walkway connecting the southern portion of the east-west stands.
There's a lot of upgrades to be had to attract younger people. As long as they can tolerate watching only the second best football league in the world with all the substandard athletes
