Some time ago, I made arnoured variants of Lucia de la Vega for "Ardent". Her model is a variant of "50_33Petra", alias Petra Boriquena. So it should be easy enough to put Lucia's armour onto Petra, useful because if you pick Petra as a FreePlay character, by default she is "Swordmaster" with gold armour.
Another "Swordmaster" FreePlay character is Juan Esteban, whose model shows gold armour even when he has none, so I made variants for him too.
However, the variants of Juan Esteban are subject to approval from @Bartolomeu o Portugues because Juan Esteban is a character in the "Bartolomeu" storyline. If Juan Esteban gets these variants then, to appear as normal with gold armour in the story, he will need to be given actual gold armour. That will make your duel with him more epic!
