The-Digital-Picture hacks EF-RF adapter to make *all* EF lenses work with RF teleconverters

I modifed the Commlite, and took out significantly less than what you did. Posting here so other can see what is needed. I opted for a mechanical file and a sharp knife (break-off blade type) to modify it.Commlite.
RF and EF extenders on the EF 600/4L IS II
After getting both the RF extenders to use with my RF 100-500L, I became curious about whether they would perform better than my EF MkIII extenders when used with my EF 600/4L IS II on my EOS R3. As most will know, the protruding elements of the RF extenders do not fit into the Canon EF-RF mount...www.canonrumors.com
I was concerned that the PCB had some delicate functionality in it, but as far as I can tell know, the answer is no. You need to go a bit under the height of the PCB to clear the extender sufficiently. Pictures 1 & 2 should with the 2x extender inserted into the Commlite RF adapter.

Neuro and others that are stacking RF and EF extenders: only the RF extender registers when I stack a RF 2x and an EF 2x Mk III on the EF 200-400. Are you seeing the same with your lenses?
Been shooting the moon again this evening and instead of saying 1600mm f/16 the R3 thinks it's a 800mm f/8 combo.
Clicking in the built-in 1.4x extender makes it clock out at 2240mm f/22 and the moon fills out almost the full height of the sensor. This makes it hard to track the moon as it moves damn fast suddenly and I need to readjust the gimbal head all the time
