Note to self, asking for help rarely does any good these days and eats thread space. No matter, I found what I was looking for.
Kofu doesn't get a breastplate, instead she gets steel-silk armor. If Leprechauns are smiths of unmatched affinity, then it should not be impossible to do things people might think unthinkable with armor, metal that is thin as silk, and yet still stops a direct knife to the stomach (Impact is still obviously a given, as is soft padding underneath just in case.), it also gives me some free rein with the torso than to give the standard breastplate. If anything, I'm half-tempted to add some Latin to polish the design before scanning and working, Kofu, Fabra Gladiatrix, has a nice zing to it, conveniently meaning Artisan Swordswoman.
