Nicely done 3D!
A couple of quick thoughts upon just starting to digest the idea:
1) I am reminded of Urban Shocker's call for a Facade District, where the best of the city's doomed older buildings could have their facades (literally) removed to and reassembled: this would be the perfect place to do it.
An example of one of those buildings is one that is shortly to fall to make way for 1 Bloor East:
I'd like to see the facade of the building furthest along to the south transported to your square - love that third floor window - and there must be others deserving of further longevity whose time is being threatened right now by 'progress'.
My own inclination is not to build 'instant old' in this city (or anywhere really): faux historic architecture nearly never succeeds. You may have entitled one of your points
Denying Disney, but the truth is that Disney does faux as well as the best of them, and it still screams faux. I agree that the Yonge facade of the Eaton Centre is wretchedly bland and appallingly monotonous even as it tries to break up that facade, and I am glad you mentioned it, but unless the developer of such a proposal hires a number of architects, and without some actual old facades grafted onto new frames, I cannot see this working as well as you hope it will. So, the next two points are:
2) Only use real historic facades for the buildings that you want to look historic. Have the City grant density bonuses to both the developer of this square and the developers of the place where the historic buildings are now. The bonuses will theoretically pay for the cost of the dismantling and reassembly of the facades. In the end you have a square that saves and celebrates the best of what this city has been, and in 10 years you don't have motor mouths like me wandering about screaming "it's all fake, fake I tells yah!"
3) Hire a number of architects to put it all together. Sure, have one firm overseeing the assembly of it all, but make sure that there is typical urban variety in the square by employing variety in the first place. I would even go so far as to say hire a couple of less august firms (G+C, Varacalli, etc. and give them a couple of smaller buildings) just to make it all look believable. (If there isn't some mediocrity around the square, it wouldn't feel like home.)
Anyway, want more squares, love this idea overall, looking forward to people watching and dining al fresco here with the sounds of the fountain splashing away in the background, and especially looking forward to the espresso and Courvoisier.
Cheers!
