If Caffeen Man said it is ok trust him.
As far as Santa, I have found that tool catalogs left out on the coffee table or what not, when left at the right time of year, with an item circled on them, somtimes are forwarded to Santa by mysterious means, and appear under the tree Christmas. Now I do not guarantee this to be a sure fire means of comunication by any means, but it has worked on occasion for me.

As far as the control horns I do have an idea.
Using a strip of carbon fiber stock say 1/2" thick around an inch long and 1/16 to a 1/8" thick. Drill a hole to match your diameter of your rod or tube stock, centered 3/8 of an inch from the side and one end. Leaving 1/8 of and inch space above this hole from the backside cut a wedge of material that resembles the normal taper of a control horn. Drill the material with holes inline with the center of the tube, as you would have in a normal horn. Use a file make a notch of 1/32" in the control horn you have made, where the rod will pas through the control horn. Now score a grove to match this on the outside of your tube so you can you a short piece of 1/16 carbon fiber rod stock to fit in the notches you have made to act as a key to prevent the rod form turning in the hole in the horn. Apply epoxy to the rod insert the key and slide you horn into position. Now wrap both rod next to the horn with carbon fiber thread embedding the thread into the wet resin. Cross over the horn from side to side several times as you wrap the tube/horn joint with the thread. Wipe as mush of the excess resin away as you can then let it cure. The horn will now be part of the tube you will not have to worry about it spinning on the tube. I have been told that carbon fiber can be machined in a similar fashion to steel so the holes in the horn for your controls to attach should not be an issue. And where carbon fiber works well under compression I would say it should hold up fairly well. Note: if you would like to use pull /pull types of controls this would be easily adapted for that by just extending the material both above and below the tube for the other horn. You can keep all of the centers lined up and totally eliminate the possibility of any ackerman effect so your control action is totally symmetrical.
