I checked in some code to do that. I whipped it out quickly, so it's not
complete in any way. It provides a M-x vc-status command which is the
replacement for vc-dired. 

It can only be used with Mercurial for now.

You can mark/unmark files, and vc-deduce-fileset knows about them. So
you can run C-x v commands in the *vc status* buffer and they will
take into consideration the selected files. (I only tested vc-diff).

As you see the code is very simple. Adding faces, more key bindings and
more fancy display should be straight forward.

Now, I cannot lead this development, I don't have the time to do it at
the moment.
But I am happy to help further.
