[XeTeX] Question about emulated font features.

This is timely as I was thinking of experimenting with a small degree of 
font expansion for main text in a Greek edition.

In a Windows installation, is there a relatively simple procedure for 
replacing 0.996 with 0.997 (e.g. just overwriting a file or two with newer 
versions), or would I have to reinstall XeTeX completely?  (If the latter, I 
think I'd wait for the next TeXLive distribution.)

Best wishes
