Would it be possible to add support for mods that provide quality scaling to locomotives, such as More Quality Scaling?

From my understanding, they essentially create additional locomotive variants that are hidden, and then when a quality locomotive is placed, it replaces it with the corresponding quality variant. This seems like it should work with MUTC, but it doesn't appear to.
If this needs to be requested on the other mod's side, I could post a request there instead.
Edit: I tried to create a url hyperlink, but I guess I didn't do it correctly.
