Re: EF extender stacking

It is the Canon EF 2x II which is the only stackable extender.  It can stack with any of the three EF 1.4x extenders.  The EF 1.4x goes on to the camera body and the EF 2x II has a bigger rear opening to fit onto the protruding front element of the 1.4x.

You can even stack the EF 2x II on top of the EF 2x III.  So you should be able to stack the original EF 2x onto the EF 2x II as well.

Not sure how that fits with your RF plans.
