Unfortunately I would say it is not reasonably possible. If you want to poke around client.master.db, feel free, but you must make a backup beforehand.

The stuff in client.master.db is replicated in client.caches.db, and the 'master' mappings records are in client.mappings.db, which are again replicated in the caches db. You'd likely have to change ids or definitions in multiple locations to make this work without errors, and all your tag counts might need to be regenerated since we are talking about a merge rather than a rename here. With few exceptions, the database just isn't simple enough to edit a namespace by hand.
