I think it may be difficult to add seats to the one side of Tim Hortons Field as it will impose on the street. There may also be an issue with how the temporary stands disrupt the access to other parts of the stadium as I believe the staircases leading to main grandstands may possibly be effected by these structures.
There is a possibility these grandstands may only be accessed from temporary gates with their own concessions and port-o-potties. That shouldn't be an issue on the south side of the stadium with the expansive podium, but it will likely be on the north side given the restrictions in site space.
We could end up seeing a proposal of a 30,000 seat Grey Cup. Not a good look for the league or Hamilton with a stadium that has come under increasing scrutiny over the years for the countless defects and shortcomings.
As for Skydump, it's has dramatically fallen behind most baseball stadiums in terms of fan comfort, amenities and revenue-generating features. The seats are among the most cramped in all MLB stadiums, and due to the original multi-purpose function of the stadium, feature flawed sitelines. An example of this are the seats down the first and third base lines in the lower bowl. In most other MLB stadiums the seats are properly oriented towards the infield as one moves further out towards the foul poles. Check out Suntrust Field in Atlanta for a good example of this.

Overall, it makes for an uncomfortable experience for the ticket buyer.
Bleachers might be the worst in MLB as well. The 500 level seats are a joke and should be closed permanently, while the 100 and 200 level seats feel like you are sitting in the cavern...bleacher seats should be open air, soaking in the sun and the elements which is basically anti-Rogers Centre. To compound the problems, current stadiums have now made bleacher seats - which were originally viewed as a cheap baseball ticket - an exclusive affair with a good portion being expensive club seats. This is something Rogers Centre lacks.
It also lacks the number of high-end, close-to-the-action club seats that more modern baseball facilities enjoy. Sure, there might be a few hundred seats like that at Rogers, but the newer stadiums have THOUSANDS of those seats in the infield. Club members also enjoy a number of different club lounges and restaurants that are lacking at Rogers Centre.
There have been discussions of plans for Rogers Centre last year ranging from $250 - $500 million but there has not been progress, at least not that I have heard. Given how cheap Rogers is, having spent a measly $50 - $60 million on renos in the nearly 20 years they have owned the Jays, I am skeptical if this will come to fruition. If it doesn't, the club will certainly fall further and further behind other clubs in revenues.
Renos are the only realistic option to solve the future revenue issues at this point given a new domed stadium would exceed $1 billion (see new Texas ballpark). The Jays will not be gifted another publicly funded stadium.
