HSL routes seem to be there as GeoJSON already. GeoJSON is what we already use for the buildings, and what vizi 0.2 uses also in the Cholopleth (area vis) plugin, so it would probably be straightforward to add routes and/or stops to the public transit vis as well.
http://www.pubtrans.it/ has e.g. "HSL line routes (paths) in GeoJSON format."
