I often avoid split elevator halfs as redundant anyway and frequently reinforce the tie between the halfs expecially for my higher performance pylon airplanes.

If What you are suggesting is some sort of loop for other rod to go through seems totaly counter productive of what the carbon rods are for in the first place (a flex free system with zero potential for any aerodynamic blow back of the surfaces).

If you are going to use two servos as in your drawing then the solution is to not mount the servos on the same rails but one deep within the fuse and the other higher towards the access. This should allow clearance where they cross.

I always do this with my warbird pylon racers except If neccessary I convert to a single servo and make sure the connection between the elevator halfs are diving board strong and will not twist. The rudder servo and elvator servos often just behind the wing are crossed as in your drawing and one servo is deep in the fuse the other higher up. Allowing arrow straight carbon pushrods from servo arm to surface horn. The differance in how much better the airplanes fly and handle is amazing compared to the wet noodle pushrod systems so common today.
