I just picked up CJ's Stormcrow TC/B and got to remembering with the old 3050 Omnis- or perhaps later resulpts- shared arms to let you mod them easier.
IIRC the Nova, Stormcrow, Gargoyle, and Executioner all shared arm options. I am not sure if they all will be able to share arms with the new KS minis but it appears the Stormcrow and Gargoyle will be able to share where suitable.
Can we get alternate arms from IWM to start making our KS mechs alternate configs? At least the Stormcrow's TC/B arms?
