Unless TPR has an updated version, I would guess no. Generally its pretty rare to see a route updated past original release. The last major efforts at that tended to be between '04 and '09. Once the major changes started coming between '09, '10, and '12 people stopped because of the massive amount of work involved. It got to be an easier proposition to just create a whole new route, but alot of creators couldn't face doing all the work all over again. I certainly don't blame them. If you have the route now, why don't you take a shot at upgrading it yourself? Just make a back up copy first. It'll be a learning experience, and probably fun too, just don't focus on "Whats left", focus on what you want to fix/upgrade.
Good Luck,
