This sounds like a very bad idea. The Skyhawk has a delta wing, but it is NOT a delta plane. Up aileron will not give the same response as up elevator. This "tied control" was a big fad when the first small foam jets came out. I had a Wattage F86 Sabre that had it, and it was a dog. Up elevator also gave up aileron, causing the wing to dump lift and splat during landing flare. Conversely pushing the nose down gave a "flap down" effect, boosting left and also making the wing more prone to stall. The obvious response is "then reverse the coupling"... no, don't do that neither. The elevators might be small but they have a much longer lever-arm from the CG than the ailerons. If you need more elevator effectiveness use more control throw and/or shift your CG back (a little bit at a time). Beware that CG position is critical for jets, where the lack of prop wash means you have reduced elevator effectiveness at low speed. A forward CG works OK at high speed but you'll struggle to keep the nose up at low speed.
