Since other restored cars exist, I'd say restoration is probably out of the question. Anyone interested in a restored car could purchase or use cars that have already been restored. I also know of at least one Ex-B&M RDC that's still in passenger service!
The railfan in me clinging to the last drop of hope which may or may not exist, probably not: If someone (The T, MassDOT, the feds, etc.) were to restore them, my guess is they'd be sent to the Hobo for the work. I don't see the T footing that bill, however.
What I'd like to see happen, is a spruce up of the exterior, which wouldn't require much in the scheme of things. Gut out and remodel the insides, and replace the office trailers on track 12 with them. It would be of some cost, but it could provide a greatly improved crew room and station operations office. Plus, to have two old Budd cars sitting at the far end of the station as though they're berthed would be classy!
Realistically, my guess is that they're in limbo, where they'll remain until someone gets the idea that something needs to happen with them, and they'll likely get moved to wherever they will be scrapped. The one nice thing about them being there, though, is that they are no longer out of sight/out of mind. They've spent the better part of a decade out in the open and in the public view, so the chances of something happening with them are far greater than they were when the cars were sitting in Billerica.
