I would say no. The journal file stores pages referenced by page no and when replayed will write those pages back to the main DB at the appropriate physical offset. Although the content of your DB's at a logical level may be the same, it is unlikely that they will be exact copies at a binary level so replaying a journal to the wrong DB would almost certaibnly cause corruption.
