I have used AIRmatic LCA's on my ABC-equipped S600. They do fit. Turns out you don't need to bother with grinding off the anti-sway bar pins.
Note, though, that the angle is just slightly different from using the actual ABC LCA's. Probably not a huge difference, but I haven't done that particular head-to-head comparison (my car got the coil spring conversion almost four years ago).
