>>5262710>>5262725They're definitely gundam kits in the shape of anime girls, in my opinion. The only thing that really makes them shinki like is the fact that Koto loves releasing weapon addons for the Frame Arms line since they're not stuck to a continuity like Gundam kits.
The armor itself isn't removable or modular like a shinki, but it really depends why you like shinkis. If you like the mecha musume feel, then you'll love these, but if you love playing with the weapons and armor, I'd think twice.
I finally just snapped my Stylet together. She could use a Gundam marker for panel lining, but I don't feel the need to paint her one bit. Currently, the back of Stylet's instruction book has me VERY interested in kitbashing. Maybe make her a mega melons and cross her with a B-52?
