Convert resource-fork fonts to .dfont?

I'm trying to manage many font files which are either data-fork files (.ttf, .ttc, .otf, .dfont) or resource-fork files (Font Suitcase and PostScript Type 1 outline font). The data-fork files are nice to deal with on the Terminal command line:

-- I can run diff on two folders and identify files only in one folder, only in the other, files in both which are different and files in both that are identical.

-- I can use tools like zip and rsync to do manage files.

The resource-fork files look empty to the file system.

Is there any tool (free or not too expensive would be nice) that can take a whole directory of Font Suitcases and associated PS files, and for each suitcase create a dfont file which contains the bitmaps and PSs in the datafork of the dfont file?
