Duplicating a file

Is there an easier way to duplicate a file based on conditions? I've been trying to copy & rename it, but the copy tries to execute first, and Hazel complains about the duplicate file.

I know you can copy to a new folder, but not copy to the same folder?

The basic workflow is I can have a file, which may or may not have some text inside it. I need the original file to have one naming convention, but if the text is present, then I need a copy of the file because it will have a different naming convention.

No way to do it now without copying it somewhere else, renaming it, then moving it back. An alternative would be to create an alias.
