No.  The problem with blurred reflection is not a resolution problem, if 
it was you could render the scene at larger size (without aa) and get a 
nice image.  Blurred reflections is about blur, i.e. averaging of color 
values.  This is not unrealistic at all, in real life the averaging is 
mostly matter of interference, diffraction, etc.

And aa is not designed to generate blur, it is meant to diminish 
aliasing artefacts due to the discrete sampling of an image.  The effect 
that it generates blur in your images is in fact only an unintended side 
effect.
