parallel to the floor and looked at it from above, you'd see that one side
was considerably less convex that the other.

Jim,

Lack of a symmetrical profile could be  a problem.  The more convex surface
probably may lift sideways more than the other side, causing a yaw that needs
to be compensated for.

The Vertical Stab on the IV was fairly symmetrical, as I remember it.

On the other hand, the P-forces of the prop sweeping in a spiral motion
around the tail probably do the same thing....Bottom Line:  What does the
factory support say?
