Update on Portals location:
I'm not sure this is as possible as I was thinking. Basing things off the B and C portals, we'd want ~500 feet of travel to get down to the right depths. That's just not possible without major rework on either end.
On the south end, you'd have to start your portal almost in the middle of the Grove Hall intersection and by the time you get down to the Washington St intersection you've got almost enough space, coming in at a bit under 400 ft. It's possible that some reworking of the grid here could help (such as allowing a central median/portal across the Washington St intersection similarly to the Geneva Ave one), but I'm sure the community response to such a project would be harmful to the project.
On the north end, I'm completely stumped. It seems like you'd be able to do the same thing with turning Hazelwood into a southbound-only connection to Warren, but you're basically at MLK by the time you're up high enough, pushing your platforms even further north.
The extra portal length turns a 3000ft station gap into a 4000ft one. That seems too far without an intermediate station, and a station box on Warren seems like a cost blowout waiting to happen. I'll stand by the pitch as "Crazy", but it's definitely moved towards the harder end for me.
