Hmmm. Whichever boon you get for her(if you get a def or res boon) refine her weapon for the same, and give her either the DD or CD seal(CD if she's Res, DD if she's Def) and you'll certainly have one bad mamma jamma.
I think with IVs like that, it would be a worthy sacrifice of your OG Hector. I'm reluctant to get rid of mine. +HP/-Def. Not the best, but the extra HP means he's better equipped to tank mages.
