I think this would be a great route as we currently don't have any SWR in the game, and it would provide a lot of services with the Class 444, 159, etc.
DTG have posted some advice for anyone making a route proposal here https://forums.dovetailgames.com/threads/matts-advice-on-tsw-suggestions.86336/ Although to save yourself time, you may wish to search the suggestion forums as I believe this has been suggested before. You could save yourself a lot of time by just adding a supportive comment to an existing thread.
