Did I send you the cr2 I made with the 2-ways kick+spread JCMs? I can't remember now, it seems so long ago.

Yes, you did.  Right! That's long time ago.  It took me about few hours to make a good JCM.  And I put few hours into 3D in a week.  Now, you understand why I'm so concern about how many JCM I need to make.

With you descriptions, I think the 2-ways JCM is independent from the JCM that made for the 2 rotation directions it covers.
