I don't know of a way to do what you are asking. It seems to me like configurations of the parts in different sizes is the best way to accomplish what you want. Surely you wouldn't need infinite variations, or else that would mean your table on the drawing has infinite rows, which would make it difficult to fit on a page. Even if there are infinite potential sizes that might be needed in the future you don't need to create them all up front, you can create (or have everybody create) a new configuration for each new size as they are needed.
But maybe someone else knows of a way to do what you want.
Edit: I just re-read your post and realize maybe you were saying you don't want to let the users create configurations in the original files. Any chance you could have them come to you whenever they need a new size and you create it for them?
With the configuration publisher you could probably set up an easy interface for people to create the sizes they need without needing to dig around in the part features. I wonder if there is a way to make the part read only except for what is set up in the configuration publisher? That would be cool.

If your search for posts by Mauricio Martinez-Saez, I think you will find that he has worked out how to do what you are asking As I recall, his work is aimed at projects that are similar but not tied to one another, so all the drawings and files are unique.
