ScaleRail

What is the best procedure for replacing already lain track with ScaleRail? I've got 168 miles of mainline, branchline, and two major yards that I want to replace, preferalbly without having to relay all of it.
I'm thinking replacing the Kuju rail references with Scalerail ones in the Tracks.bin and TrackRules files should do the trick?
