hmm... I would go with "generic" Yu-Jing spec ops https://store.corvusbelli.com/wargames/infinity/miniatures/gui-feng-spec-ops I think this model is looking closest to Yuriko, just paint in in JSA clolors... and maybe get some "female" head
The Kaizoku Spec Ops mini is a good candidate. It looks like a badass Keisotsu, which is basically what Yuriko is. It isn't likely to be confused with anything else in the JSA roster.
What is it you dislike about Yuriko’s model? Or, alternatively what would you like to see aesthetically? Without knowing why you want to proxy it’s hard to suggest an alternative. There’s a big difference between, for example, “I like her look, but don’t want to get the dire does box, so I’d like a proxy that gets close to her appearance.” and “I’m not a big fan of her look so I’d like an alternative for a female keisotsu engineer.”
Basically that. I do like the thought behind using a Kaizoku model, but they don't look feminine at all...
If you don't want to sculpt your own hakama onto a different model, there's not a lot in the way of single blister models that have them these days. you could probably still get one of the old Raiden sculpts or the Haramaki Missile Launcher. But none of them look feminine and you'll need to do a weapon swap and maybe a head swap if you don't like their helmets. iirc Shinobu comes with a separate head, but then you're buying two sculpts. That being said, you could always convert her to a regular oniwaban, and the Raiden helmets are actually fairly similar to the new Oniwaban style,so if you bought both and just did a head swap you'd be in pretty good shape and would just need to worry about the Raiden's gun. Alternatively, if you already have the JSA army box, I can't imagine it would be too hard to fabricate some 'fins' to put on to the female keisotsu combi sculpt and just use her. If you're not locked into hakama, i'll try and think of some good single blister out of faction options and post back here.
Ok, did a bit of looking around: Over in Yu Jing town there's the Daoying Hacker whose torso armor is comparable and whose chunky thighs mimic the silhouette of hakama without actually being them. Spoiler: Daoying There's also the Kanren Hacker Spoiler: Kanren In Haqq town you could try the Namurr. If your sculpting game is good her legs are far apart and should give you plenty of room to sculpt on some hakama. She's also a nice looking model as is. Spoiler: Namurr In Ariadna, 6th airborne ranger has an engineery look to her. Spoiler: Ranger Nomads have got Zoe and Pi Well, though you have to buy them together, they're still cheaper than a dire foes box; Spoiler: Zoe And an honorable mention I guess for Miranda Ashcroft. She fits more into the Aragoto biker aethetic with her leather jacket and stuff, but she doesn't have a lot on her sculpt that physically sticks out so she might be a good base to sculpt over to add armor or to convert if you're into that sort of thing. Spoiler: Miranda
Not going to lie, popping one of these on the table, painted in proper YJ colours, and telling your opponent that it's Yuriko Oda (or any other JSA trooper, really) without any irony would be beautifully clever.
