There are always trade-offs. To improve service to some areas, others may have to take a hit to theirs.
The trains currently serving that inbound evening window where there will be a gap have a ridership out of Walpole of 8 people combined. So virtually nobody is using the currently offered service. Maybe changing it to run out of Foxboro will draw more ridership?
As for any infrastructure changes at Walpole station, the MBTA is probably looking at it but they can't commit until the pilot is deemed successful. There's also the problem of the historic station building. Any changes to the station will also require a full high-level platform to replace the existing one on the Franklin Line side. So it's not any easy or quick solution to add the stop on the Foxboro side.
