It seems that I have seen some things that implied this could be done.  
I was not interested at the time and did not pause to look into it.  If 
it is possible, it might be done in modifying the OS X app bundle by 
adding some directories, by moving over the OS 9 app and by editing 
some files.

Look at app bundle specs.
