I attempted a very crude experiment using a satellite image off Google Maps, Kanto's proposal and PS to see how a re-alignment of West St. would work to fit in the new proposed tower.
First I had to scale the proposed image and rotate it to fit the image from Google Maps. Then I made a rough attempt to move West St. exactly as is, in order to by-pass the new proposed tower. This is what I got...

Re-alignment of West St:
As you can see my rough attempt to re-align West St., there is not enough room between the proposed tower and WFC.
