It is something that sounds like a good idea until you actually try to do it and realize unless the building was designed that way from the start it is very hard. Bankers Hall has the under ground conference centre for this future purpose.I'm actually pretty sure this was the preferred solution sought by Green Line, I can't find anything right this second but I remember hearing repeated mentions of trying to integrate station entrances. Would definitely come down to property owners and technical feasibility
