Matt:

Running power to the coffers is the biggest issue as there is a matrix of rebar, #18 radially and #9 linearly, roughly 2" behind the surface of the concrete. It wouldn't be a cheap job to do, but think it could be done as the rebar was very accurately placed. All of the structural plans of stations had detailed drawing that show the rebar layout.

Getting the power to the coffers in the stations north of Farragut North and in Rosslyn would not be an issue as the top and sides of the vaults in those stations are accessible.
