You mean yaw through 360 deg? Sometimes called a 'flat' turn.
It will. Eventually. The catch is that the size of the forces that can be generated by rudder is a lot less than can be generated by the wings (small fin/rudder vs. big wings).
The a/c has inertia & directional stability so will tend to return to the same heading if disturbed AND the disturbing force is removed. Keep the force there however, and it will eventually achieve a new heading.
Next time you fly on your own (pax don't usually like playing like this) make sure you're below Va comfortably above Vs. Gradually apply up to full rudder. Hold the rudder for 10 or 15 secs & release (under control). Keep the wings level through out. The a/c will stabilise on a new heading.
Secondary effects mean that you would have 'fight' these wtih crossed controls to maintain a wings level attitude. That leads into potential nasty effects if the a/c stalls during the turn.
The fin/rudder could be increased in size to better allow such turns but that in turn can have unfavourable effects.
Overall rather less efficient than a normal, banked turn.
Also the skidding sensation is not as comfortable as a balanced turn that maintains the force acting normally.
