To paraphrase Larry Wall, "CVS has to better for something :-)" [1].
Moving ,v files around is a hack, but there is a delightful simplicity
and transparency to the hack that just cannot be matched by these
newfangled VC systems with their fancy-pants high-performance binary
databases.

But seriously... if you want to carry the entire history of a file
from one hg repository to another, take a look at the bundle and
unbundle commands.  I think that is close to what you want.

Of course, you will probably have to add another revision to move the
file to its correct location in the new repository, but that can be
done after unbundling.
