>>11412894The compatibility is interesting, legs are compatible but the shoulders are on an older style gundam double peg instead of the usual modern bandai ball socket. Easy enough to still use the arms, and as a bonus the wrists are the same size, so you can have big hand girls and small hand knights. The shoulder armor is a bit wide but IIRC there was a kit that included a narrow back adapter for using the shoulder armor with 30MS. Just got my Liber Knight so I'm goofing around, I used a custom hair piece with my Tiasha, but the neck is still compatible with regular sisters.
