>>8933870Rin and Dorthey are essentially goth versions of Asuka and Rei aesthetically. You could start with those. That one Idol Master is the closest Misato looking head and face I can think of, unless you want to fudge a short haired Misato with one of the figmas of the Major.
I guess just browse Manda and Amiami's used figma and see if anything is good parts fodder. Gothic Lolita or western goth would be a fun Figma Styles, but even if it was announced tomorrow, we wouldn't see it for at least a year or more.
