Looks like you have the later unit, so yes you can Y off the radio packs.
I understand there is not space for the carbon clamp. The hatch with wood spacer is what is really holding it down, the silicon is a secondary fix/isolator.
You don't have to remove the former, just have the pipe as high as possible in the fuselage at the rear.
Hopefully our first one will be finished soon and I will post pictures.
