Looking at the solid trailing edge stock, you could simply cut out short chord but long length ailerons, while still leaving some balsa stock for the aileron header. I did that with a Herr Cherokee which flies really well, with a pretty short aileron chord length but long span length. On that plane, I had to fill the header with 1/8" square stock inset, since the trailing edge was fabricated from sheeting ran along the outer surfaces of the wing. The very short (roughly 3/4") aileron chord is actually quite effective, given their long length.
For the torque rods, the TE stock could also be cut away and then capped along the top and bottom with balsa stringers, to provide a channel for the rods. The cutaway portion could then be glued back onto the stringer capping. Since this capped torque rod channel lengthens the wing chord slightly, it allows you to glue a cap strip onto the ailerons at their hinge line and lengthen their chord a slight bit, so that they will be aligned across their trailing edges.
