I just don't see the point of pushing for elevated through low-density outlying neighborhoods. There's just no value proposition, and lots of resistance.
Also, why would you run a shuttle from Back Bay to South Station only. Where are you going to turn it? Let's fixup Worcester, electrify it, infill it and run short-turn service to Brighton/Newton. Increase frequencies on every line passing through BBY and you've got your "shuttle."
