It's not a problem to add the pilot and CPG into the cockpits. However you'd really need a TIR and the controller animations would need to be locked in place. With some slight positioning adjustments it'd actually look pretty good. Animations could come later.
You can see how many of the switches in the CPG panel are blocked, actually some of them are blocked by the TEDAC anyway, but adding pilot models certainly makes operating the front seat more difficult.
Cheers
