I don't think so... not without some serious study of the different makes and knowledge of what each of them uses as "standards"....
You may find some by going to
http://www.mouthpieceexpress.com and reading what's there about the different types.
The alternate (and highly recommended) is to find a shop that has a Warburton dealers' kit and work through it. That'll pretty much get you to the right cup diameter, cup depth, and backbore as fast as anything. With the different shank designs you can also see what adjusting the gap will do....although you have a horn with an adjustable gap already?
