I did some testing with the gorgon too but I prefer those magic path to the one you use : awake with A4E4N4. Any build with E9 works quite well too, since sending her "naked" and is enough to take care of most indies !
The reason is I find her much more powerful with some air magic is because she can cast cloud trapeze, mistform, and invulnerability, and you have easier access to air items. Which are great for the gorgon, since they improve defense by a lot, and high protection can be taken care of with invulnerability. That gives her easily 30 or more defence and protection. I usually use her to search for the few necessary air sites that you will need to forge the air items though, and take her awake.
The gorgon is a very strong pretender, and there is little you can do to get a wrong build with her. The downside is that she locks your magic diversity.
