By "round trip time between A and B" you mean the time to get from
A to B and back to A?  And is this time the elapsed time, or the
coordinate time, or what exactly?

And if A and B are points, you haven't said anything about what
frames of reference are involved (and if they are frames of referance
you haven't said anything about where the messages go).

So... I don't see how you can conclude anything at all, because your
hypothetical is nearly meaningless as it stands.  Taking the statement
at face value, and if we assume that you didn't leave anything out (ie,
about swapping frames), and that A and B are points, then what you've
stated doesn't even come close to proving there's a prefered frame,
since you haven't attempted measurements in more than one frame.  You can
"avoid a prefered frame" because all your statements are compatible with
having been done in a single (non-prefered) frame.
