No.
There can only be one VC for an aircraft, so can't use both the csx772_pax_interior.MDL and csx772_interior.mdl at the same time.
The reason there is no VC with the Cabin is due to the polygon limitations in FSX. Adding the VC to the Pax Cabin would exceed the limitation.

We have asked for a VC with a partial Pax Cabin (VC + First/Business Class pax cabin), but nothing has become of that yet. :(
