Surely in this day and age it is possible to have platform edges which automatically extend to meet the tram? In New York when the two subway systems were combined, automatic ramps were installed so that trains from the narrower system could use stations from the wider system. Some stations still have them.
Given the height of the trams plus OH is 3.8 m plus and the tunnels are singel bore then the width of the trams wont be an issue. Its platforms and at grade and elevated structures which are the issue.
