Okay, the more I think about this, the more it does make sense. I believe the big CBR building will be like the hub or central station with 3 branches leading to DHS, International Gateway, and AoA/Pop station in the northern parking lot.
I have redrawn the map to include what we know now (yellow) and what we are suspecting (light green)

A couple of points about this:
1) I suspect the International Gateway terminal will be built on the land where the old tram turn around is. Although technically there is enough room between BC and Epcot Resorts Blvd for it be built on that side. EDIT: It has to be the International Gateway side, because corner of Boardwalk Resort Convention Center is blocking a straight line from the tram pivot building seen on the permit to the pad next to BC:

2) The line to International Gateway will pass right against where the Ratatouille building will go behind France.
3) I suspect the gondola cabs may be enclosed with similar to Hogwarts train due to the fact that they will go over backstage WS, unless they spend money sprucing up the WS backstage areas that will be visible.
4) Could CBR be in for a total overhaul in theme? I have never seen a gondola in the Caribbean
