Re: change faces interactively

Sorry for my poor explanation.
What I want is an interactive function that turns on/off face changes by command.

Say, a buffer is in "my-mode".  The above (define-generic-mode ... ) will AUTOMATICALLY apply the face definitions to all characters as soon as the buffer is opened (assuming the mode definition recognizes its file extension).
I would rather develop a function that applies the faces AT WILL even after the buffer is opened IN THAT MODE.  
For example, a buffer is in "my-mode" but none of the words in that buffer is applied with any faces.
Now I will implement a function, (defun my-mode-face-1 ()  (interactive)...), then a certain set of words in that buffer is bold-faced.  After that, I will implement another function, (defun my-mode-face-2 () (interactive) ...), then another set of the words in that buffer is italic-faced. And so on...

If it does not make sense, please ask me again.  I appreciate it.

Not quite sure what you're asking.  Do you just want to modify a set of faces FS
so they look the same as some given face G?

If so, you can define a command that reads the names of the faces to modify (FS)
and the face to copy (G), and then, in the body of the function, call
`copy-face' to modify each of the former (each F in FS).
