[oXygen-sdk] Extending the dita framework

Hi I've made an extension on the oXygen DITA framework. I made a copy of the dita framework folder and added my own jar file which has some extensions/own implementations. After I upgraded my oXygen from 14.1 to 14.2 some icons went missing. I saw that in the newer versions some extensions changed. I'm thinking on duplicating the images in my framework folder. Is it possible to use a copy of the icons in oXygen? Where can I find them if it is allowed?
