Ok, I've made 3 extra shadow library parts. It was actually quite easy with the built-in shadow editor. You can download them here in case anyone would like to use them.
Note: all 3 shadow parts are for (currently) unofficial parts, so you should add a second shadow library in LDcad for the unofficial parts
