Hard one Vladimir, la good challenge to beat after year end.
What about something like that:
The key is the information for load LMDB CIM from a updated SLD, LMDB is synchronized from SLD and SLD is updated manually with CR content, so you maybe don't need internet connection to update CIM information on SLD.
You can check note correction on "right" solman and then load it manually to DMZ solman if you need to apply some sap notes corrections.
For mopz, and others solman basic tools (like SDCCN) you can't use it correctly without a SAPOSS snc RFC connection.
