I'd be more concerned about flow seperation at high angle of attacks
being induced by the sharp leading edge. Typically, stabilizer surfaces
have very low aspect ratios to insure that the airflow remains stable
across the stabilizers even when the main wing is fully stalled. Having
a sharp leading edge may cause problems with early flow seperation. This
might cause stability problems or even possibly some flutter. I don't
have any hard data to prove this, but I don't think you're going to gain
enough drag reduction to justify risking the potential problems.

I think you're right. Probably better leave control surfaces well
enough along, but go after the other "protruberences": Antennas,
struts, landing gear, etc. Places that you don't care if they produce
drag in a side slip but clean up nicely in cruise.
