Nobody is proposing a station east of the bridge. It's just a tail track. See the diagrams in my post above, the platforms are just the two existing ones.
You need to design the transfer time around the slowest user, not the fastest user. And no matter how well you position yourself on the bay platform, you're never going to match the convenience of the tail track option that drops you off on the same platform where the next train picks you up.
Adding retaining walls and acquiring property would definitely be more expensive than adding a second set of spans to a bridge that already has the abutments for them.
That was the image Google Maps gave me, not sure why you're getting an older one. Maybe you have 3D buildings on, they don't update 3D imagery very often.
In any case my go-to for recent images is Google Earth via its Time tool. Many cities also have their own online mapping tool that may have more recent imagery than Google Maps.
