This may be logistically insane, but would a pedestrian square or commons on Front St. between the two halls be a good idea? I can't really picture traffic flow around there but maybe Jarvis and Church could serve as north/south arteries to divert the east/west traffic along Front and Wellington around the square? It might be somewhat derivative of Faneuil Hall but you can never have enough open, public areas like this downtown, especially as the city's population and density continues to grow so rapidly.
