The Falcon cockpit would be like any of the vehicles that Hot Toys has already released. It enhances the collection and display.
Just take a look at the DeLorean and Marty figure. Both compliment each other and Marty looks fine in the car. (although I would display him outside of the car so more of the interior could be seen.)
There are so many display options available with the Falcon cockpit, from OT to NT. I might initially go with Leia and Chewie in the cockpit, with Han standing on the other side of the door.
