Asside from copying the database local, I don't know that it's possible.
You said you tried moving it to the local settings folder, do you mean you moved it to a local folder that contains MAP.INI or do you mean you copied it here...
C:\Users\<username>\AppData\Local\Autodesk\Fabrication <####>\CADmep
If either of those don't work (those tricks use to work better years ago), I think your only option would be to copy the entire DB locally.
I'd be cautious about swapping out SETUP.MAP. I know a number of things to controls but not everything because no matter what you seem to do in the DB, SETUP.MAP get's updated so it, above most other files makes me nervous.
