Well, for the moment, the only one you can get (I think) is the one currently
HERE so if it doesn't have a VC, I think you're kinda outta luck.
And you can't add a VC to an already compiled aircraft. The virtual cockpit is part of the mdl file, so you would have to decompile it and make it into a file that can be read by some 3D design tool and then add the VC, THEN recompile it! Trust me, it would be much more of a headache than its worth.
You're best bet is to just wait and see if someone does one with a VC in the near future. The problem is really that no one has the faintest idea what the cockpit will actually look like yet.
