It's a great Idea but that would be a lot of lines for Union Workshop to create. If they do make another Japanese DLC I would suggest they focus on the Odakyu Odawara line from Shinjuku to Odawara since the line was in the Micosoft Train Simulator and they can also include the Hakone Tozan Line from Odawara to Hakone Yumoto as a service variation.
I've been on the Odakyu system from Odawara to Hakone. Great trip! I think it would be a nice route to see.
