I found this in a old message from @LiliArch with me about the subject and I think it may still be good. Please report back here to let us know, one way or another. Don't use the Steam Workshop versions of any of the below listed mods. Use only the mods linked to in this message.
Presumably with these instructions, you'll be installing TSLRCM, then installing M4-78 Enhancement Project, then (and only then) using the instructions below. It's a good thing I had a copy of the "Coruscant Jedi Temple Expansion" mod saved so I uploaded it to a DropBox.
TSLRCM + M4-78 EP + Newbiemodder's Korriban Expansion + Coruscant Jedi Temple + Coruscant Jedi Temple Expansion installation
1. Follow the M4-78 EP + Korriban Expansion compatibility instructions.
2. Install the Coruscant Jedi Temple mod.
3. During the installation, you will get a warning "placeables.2da already exists in the Override folder. Skipping file..." That is normal and nothing to worry about. If you get any other warnings, however, you have a problem.
4. Drop the files "a_galaxymap.ncs", "galaxymap_p.gui" and "tr_leave_ehawk.ncs" from Jedi Temple Compatibility fix's M4-78EP folder to your game's Override folder, overwriting the ones in there.
5. Drop the file "changes.ini" from Jedi Temple Compability fix's "Jedi Temple expansion changes.ini" folder to Jedi Temple expansion's tslpatchdata folder, overwriting the one in there.
6. Run the Jedi Temple Expansion's installer (make sure it is the one whose tslpatchdata folder you dropped the changes.ini into).
7. Pick a savegame from before ever entering Korriban, and enjoy your game.
