Great post
@Fallsview! I agree with all your thoughts on the reno.
Incidentally - I don't have the link but I read SOMEWHERE (perhaps on AndrewStoeten.com) that replacing the current blue seats with larger, green seats was in the cards.
As you say, I'm sure it would come at great cost, but it would be amazing to SOMEHOW open up that outfield. If it was feasible to remove the hotel (I know it was discussed how difficult that would be), remove the 500 level outfield seats, and open up that outfield wall to the city (perhaps with windows like in Miami and Milwaukee), I actually think we'd have a pretty enviable ballpark (assuming the natural grass plan comes to fruition).
I'd love a new PNC Park type stadium, but I would be almost as happy with a massive reno of the Rogers Centre. The building does have its (major) drawbacks, but the location is just too perfect. I imagine a new park would have to go in the portlands or something. Would be stunning outfield views, but a shame to move out of downtown like that.
