Horten IV elevon linkage
After toying around a bit with this concept, I've come up with a rather easy method for what appears to be a very complex linkage arrangement. Materials are brass tubing, music wire and solder.
This prototype does not quite have the correct geometry with more deflection in one direction rather than the other, but overall deflection is good. Would require a very big arm on the servo to drive it. All do-able. Next time I'll use a drill press to drill the tubing for the axle.

Sorry, but here comes mister awkward.
Why have you made something so 'complicated' when individual servos working push rods to control horns are so easy ?
The rotating angled rod still seems to take up room within the wing section if it's for scale reasons, and you still need two servos.
Also if a totally hidden control was required, wouldn't an RDS drive be easier ?

But all that said, your mechanism is fascinating

Welcome mister awkward.
This is a scale version of the linkage used on the Horten IV. Just another unique example from a truly unique sailplane. Although my version is just a prototype, it is more robust than expected. With a little more development, it could be useful.
As you've noted, this linkage is entirely internal, like RDS. But unlike RDS, this linkage and tolerate sand, which is a given for me.
Also, multiple elevons could be operated by one pushrod. Although they are tied together by the pushrod, each elevon can have a different deflection, depending on geometry.
