Maybe something like this:

db.attach("other_db", "other_db.db")

Here's how twitter-to-sqlite does it: https://github.com/dogsheep/twitter-to-sqlite/blob/6be0ffcee24504fa2964b0e526842b8cfce7567b/twitter_to_sqlite/utils.py#L506-L511

                attach_sql = """
                    ATTACH DATABASE '{}' AS [{}];
                """.format(
                    str(pathlib.Path(filepath).resolve()), alias
                )
                db.conn.execute(attach_sql)
